Process builder cannot handle null of cross object on formula criteria
Last updated 3 days ago ·Reference W-2763830 ·Reported By 516 users
Process Builder does not handle cross-object formula criteria when that relationship field doesn’t have value.
1. Create a process on Contact using the Process Builder.
2. For the first action group's criteria, select Formula evaluates to true and enter formula: ISBLANK([Contact].ReportsTo.Description)
3. Add an immediate action (e.g. post to chatter).
4. Activate the process.
5. Create a new contact without entering a value for Reports To.
The contact is created successfully or a user-friendly error message is issued.
- Error like: A flow trigger failed to execute the flow with version ID 301xx00000000Hb.
- Debug log and/or fault notification email to process creator will indicate error: "The flow failed to access the value for myVariable_current.ReportsTo.Description because it hasn't been set or assigned."
If possible, use filter criteria instead of formula criteria, being sure to include a criteria to check that the relationship field is not null prior to making a cross-object reference across that relationship.
As an example, for the criteria given in repro steps above, filter criteria could be used like:
1. [Contact].ReportsTo is null boolean False AND
2. [Contact].ReportsTo.Description isnull boolean true
Workaround is not valid for cross-object picklist fields referenced in a cross-object formula criteria when the relationship field doesn’t have value
