Flow Error Help - An unhandled fault has occurred in this flow

Question

So, I have a fairly large process here that I am working on that includes two Process Builders and a Visual Flow. While testing this process I am getting the An unhandled fault has occurred in this flow error.

Process 1. When a Buyers_Order__c gets marked signed (Picklist Field), it will update all of the associated Cap_Cost__c records (Updating a checkbox to true). Then the second Process will Kick off on any Cap_Cost__c that is modified to have that checkbox checked. The second process will simply just call the flow which is step 3. I am passing two variables into that flow, BuyersOrderID and VinNumber.

The flow will take the variables that were passed in and do a fast lookup to find any Cap_Cost__c records that the BuyersOrderID is not equal to the one passed in AND the VinNumber is the same as the one that was passed in.

It will then loop through all of the records that were found and update a checkbox (Needs_Removed_Or_Modified__c) on them to true.

Based on the below error message that I am receiving in my email, I believe that all of this is working up until the point where it tries to update that final record checkbox. Please let me know if you need to see any screenshots or need any further insight to this process.

Error element Update_Cap_Cost_Needs_Removed_Checkbox (FlowRecordUpdate).
The flow tried to update these records: null. This error occurred:
CANNOT_EXECUTE_FLOW_TRIGGER: The record couldn’t be saved because it failed
to trigger a flow. A flow trigger failed to execute the flow with version ID
30136000000JFoF. Flow error messages: An unhandled fault has occurred in

Concept Services (0053600000306H9) started the flow interview.
Some of this flow's variables were set when the interview started.
BuyersOrderID = a023600000LQfSYAA1
VinNumber = TESTUNIT813515
FAST LOOKUP: FindCapCostRecords
Find all Cap_Cost__c records where:
VIN__c Equals {!VinNumber} (TESTUNIT813515)
Buyers_Order__c Does not equal {!BuyersOrderID} (a023600000LQfSYAA1)
Assign those records to {!CapCostsNeedingRemoved}.
Save these field values in the variable: Id
Result
Successfully found records.

DECISION: Cap_Cost_Found
Executed this outcome: CapCostWasFound
Outcome conditions: and
1. {!CapCostsNeedingRemoved} ([a063600000BhyXJAAZ]) Is null false
Logic: All conditions must be true (AND)

LOOP: Loop
Loop Through: [a063600000BhyXJAAZ]
Iteration: 0

Answer 1

In general, the flow/process builder error handling is suck, and this issue hopefully will be enhanced by SF in future.

Regarding your flow, it is not clear why you doing update inside the loop? You should: 1.Retrieve all records into collection 2.Assignment inside the loop - Needs_Removed_Or_Modified__c = true 3.Update the collection

Not sure if it will solve the issue. If not, try isolating the problem - try running only the flow for specific record by passing the parameters in the URL(try with different records). -Try disabling specific steps in the flow - by playing with the arrows - to verify where it is failing. -Try to update other field instead on the record.

Answer 2

Not sure , but it looks like that you didn't add any error handling. this step DECISION: Cap_Cost_Found Executed this outcome: CapCostWasFound Outcome conditions: and 1. {!CapCostsNeedingRemoved} ([a063600000BhyXJAAZ]) Is null false Logic: All conditions must be true (AND)

states that the record found does not fulfill the requirement as it is null / false

it might also be the case that your cap_cost records has insufficient information on it?

Your flow def. finds a cap cost records in regards to step 1 but this one does not match the criteria for step 2 as a result step 3 tries to update NULL records As per error message: Error Occurred: The flow tried to update these records: null.

you might like a decision step that if there is a record ..then but if null then Not

hope that helps the trouble shooting

Answer 3

It looks for me like you need to include also Needs_Removed_Or_Modified__c field into your CapCostsNeedingRemoved, and drop Id Equals {!CurrentCapCostID.Id} filter from record update.
