NEW from the Tether Tips Blog – Always have a decision after a Lookup/Get element to check if records have been returned to avoid flow errors.
Having a decision after a Lookup/Get element to check if records have been returned can help avoid flow errors.
As a team we like to share tips and tricks amongst ourselves, and this small “gotcha” is something we’ve come across a few times in the past.
The Error:
When a null value is called into a Screen Flow, Salesforce will display the following message:
The Flow couldn’t find the {!GetAllOpps} Records
The Solution:
When using a ‘Get’ or ‘Lookup’ in a Flow, we recommended that you look for the checkbox that says “Assign null values to the variable(s) if no records are found”. There will be many scenarios where the lookup doesn’t find a record, so you want ensure this does not cause any errors.
Directly after the Lookup, add a decision check for Null in the variable you assign in the ‘Get’ step. See below for an example of the Get and the Decision/null check. If your background is in programming, you can think of this as your “null pointer” check.
This way, we are able to display a more meaningful error message if there are no records found or guide the user down another route to fix the underlying issue.
Flows offer a huge range of flexibility when trying to automate updates across multiple related records, and with the new releases from Salesforce they become more and more powerful, and user friendly.
