Common Issues in Salesforce Flow and How to Address Them

Salesforce Flow is a powerful automation tool by Salesforce that can help streamline complex processes and boost productivity. As you navigate the exciting (and sometimes tricky) world of Flow, you might stumble upon unexpected errors, performance hiccups, or logic roadblocks. But as trailblazers, we’ve all been there sometimes.

This article will discuss common scenarios and issues that can trip up even the most seasoned Flow users. We’ll also equip you with the knowledge and best practices to avoid them altogether. Let’s get in.

#1 Using the Wrong Field

In Salesforce, fields act as organized data compartments within your records. Each field represents a folder within the database holding specific information with specific purposes.

Misplacing data into the wrong fields can disrupt the Flow’s ability to access the correct data required for processing. This happens because you’re telling the system to fetch information from the wrong storage location, leading to errors or unexpected outcomes in the Flow’s execution.

The Problem

Feeding data into fields intended for different values (e.g., entering a phone number in a text field).
Neglecting field-specific formats or restrictions (e.g., exceeding character limits).
Mapping incoming data to incorrect target fields during automation.

The Solution

Understand the purpose and data type of each field. Salesforce labels and data types provide valuable clues.
Ensure the information you enter aligns with the field’s intended use (e.g., numbers in number fields, dates in date fields).
Leverage features like “Show Available Fields” in Flow Builder to visualize and select the correct fields.
Implement validation rules or formulas within flows to ensure data adheres to specified formats and limits.
Before deploying your Flow, test it with diverse data samples to identify potential field misuse issues.

Bonus Tip:

Consider field-level security. If a field isn’t visible to the user, attempting to input data into it within the Flow might lead to errors.

#2 Using the Wrong Variable

A variable is a container that holds the value. If you accidentally use the wrong variable to store or retrieve information, the Flow won’t understand what you’re asking it to do, causing errors and unexpected Flow behavior. Using the correct variables in your Flow to store and fetch data accurately is crucial, ensuring the Flow works as intended.

For example, referencing PricePerItem instead of UnitPrice can lead to inaccurate total cost calculations.

The Problem

Assigning values to the wrong variable during data capture or calculations.
Referencing an undefined variable or one containing outdated data.
Confusing variables with similar names leads to unintended data retrieval.
Using variables with incompatible data types causes processing errors.

The Solution

Choose descriptive variable names that accurately reflect their contents.
Use folders or namespaces to group related variables and avoid confusion.
“Flow Builder” allows you to inspect variable values at different stages, helping you track data flow.
Utilize formula fields: Transform or manipulate data within variables using formulas before using them in calculations.
Test your Flow with diverse data scenarios to uncover any variable misuse issues.

#3 User Lacks Object/field Level Security Permissions

If a user doesn’t have the correct permissions, the Flow won’t be able to access certain information, hindering their ability to interact and process data. In other words, the Flow cannot execute actions due to insufficient permissions.

The Problem

Flows attempt to access or modify objects or fields for which the running user lacks permission.
This can occur due to user profile limitations, permission set restrictions, or dynamic data changes within the Flow.

The Solution

Review object and field-level security settings for all objects and fields involved in your Flow.
Ensure the running user has the necessary “keys” (permissions) to access and modify relevant data.
Leverage sharing rules or dynamic record access based on criteria within the Flow to control data visibility dynamically.
Test your Flow with users having different permission levels to identify potential access issues.
Keep up-to-date with Salesforce security best practices and updates.

#4 Null or Empty Values

When the Flow expects some data in a certain variable, but it turns out to be empty (null), the Flow becomes confused and can’t process it accurately. If Flows uses these null values in calculations or decisions, it can lead to halts or errors. Handling these situations is essential for preventing Flow breakdowns and ensuring accurate outcomes.

The Problem

Variables intended to hold data remain empty or are assigned null values, often due to:
- Incomplete user input.
- Data retrieval issues.
- Unexpected outcomes from external systems.

The Solution

Use “Decision elements” to determine if a variable is null or empty before using it.
Assign default values to variables that might be empty, ensuring the Flow has something to work with.
Prevent null or empty data from entering your Flows by enforcing validation rules on user inputs.
Identify and fix the underlying reasons for null or empty values, such as incomplete forms or data retrieval issues.

#5 Dependencies on Previous Steps

Make sure to check if the variable depends on values computed or fetched in previous steps of the Flow. If these dependencies are not met, it could lead to errors when using the variable.

For example – you calculate the total purchase amount or assess eligibility based on specific criteria. You might have a decision element that determines the following action based on the calculated total amount. If, for some reason, the calculation step fails or is skipped, the variable may not be assigned a value. Consequently, when the Flow reaches the step that depends on this variable, it might encounter an error or produce undesired results due to the missing or incorrect value.

The Problem

A variable’s value depends on calculations or data retrieval in previous Flow steps.
Issues in those earlier steps (e.g., errors, skipped actions) leave the variable empty or with incorrect data.
This triggers errors or unexpected behavior in subsequent steps reliant on the faulty variable.

The Solution

Decision elements or formulas to check if dependent variables have valid values before using them.
Handle errors gracefully through actions such as displaying messages or providing alternative paths.
Utilize try-catch blocks to handle exceptions within error-prone areas, preventing Flow halts gracefully.
Record error details and variable values at key points to facilitate easier debugging and identifying root causes.

Bonus Tip:

Consider using triggers that re-run specific Flow steps in case of errors, allowing for potential self-correction and data integrity maintenance.

#6 Unexpected Data Types

Flows encounter errors when trying to process data with the wrong type. If your Flow expects a number but the variable contains text, it could lead to roadblocks and produce inaccurate outcomes.

The Problem

Variables or data retrieved from external sources have incompatible data types with the operations attempted in the Flow.
This can occur due to:
- User input errors (e.g., entering text in a number field)
- Data import issues
- Mismatched field types between Salesforce objects and external systems

The Solution

Know the data types of variables and fields involved in your Flow (e.g., number, text, date).
Utilize Decision elements or formulas to check if data types match expectations before using them.
Use data manipulation functions within Flow to convert data types when necessary (e.g., text to number, date to string). Consider using Apex in Flow for advanced manipulation if complex data type conversions are needed.
Provide informative error messages explaining the data type mismatch to users.

#7 User Input Errors

While user input adds flexibility, it also opens the door to errors and unexpected behavior. If the variable involves user input, validate it to ensure it meets the required criteria.

The Problem

Users unintentionally enter incorrect or invalid data during Flow interactions.
This can occur due to:
- Misunderstanding input requirements.
- Typos or formatting errors.
- Entering information incompatible with data types or field restrictions.
These errors can cause various issues, including
- Flow disruptions (e.g., errors, unexpected outcomes)
- Data integrity problems (e.g., inaccurate records)
- Frustration for users

The Solution

Implement validation rules directly within Salesforce fields to enforce data format, range, and uniqueness.
Use Decision elements and Screen elements to guide users in correcting input errors.
Before deploying or updating your Flow, conduct thorough testing. Test different scenarios to ensure that variables are behaving as expected and storing/retrieving the correct data.
When encountering unexpected behavior, use debugging tools available in the Flow Builder. This helps identify which variable is causing issues and why.
