System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_EXECUTE_FLOW_TRIGGER

Hi,

I'm getting the below error when converting a lead to an opp: 
Error: System.DmlException: Insert failed. First exception on row 0; first error: 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 301D00000004I5q. Flow error messages: <b>An unhandled fault has occurred in this flow</b><br>An unhandled fault has occurred while processing the flow. Please contact your system administrator for more information. Contact your administrator for help.: [] Class.leadconvert.BulkLeadConvert.handleOpportunityInserts: line 413, column 1 Class.leadconvert.BulkLeadConvert.convertLead: line 106, column 1

I've tried hitting the URL for ~/301D00000004I5q and it throws an "Insufficient privileges" error despite me being a full admin.

Thanks,

Dan

Somehow your process builder is not running and causing an error. The flow id is 301D00000004I5q

How can I ID which process builder flow is running?

I think you can put the ID of the flow as a below URL that will open the underlying flow, where you can see the flow name.

Hi Dan,

Please use the below things and read carefully there is a some repro for that:

Lead convert fail when there is Lead (Process builder) trying to update the lead during the conversion.
Knowledge Article Number000232516
DescriptionIf you have a process created for the Lead object in the process builder, you may encounter an error similar to the one below when trying to convert a lead.

"Error: System.DmlException: Update failed. First exception on row 0 with id XXXXXXXXXXXXXXX; first error: 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 XXXXXXXXXXXXX. Contact your administrator for help.: [] Class.leadconvert.BulkLeadConvert.updateLead: line 1375, column 1 Class.leadconvert.BulkLeadConvert.convertLead: line 151, column 1"

This will happen if the process you have created for leads is trying to update the lead when it's converted. When a lead is converted, some values on the lead are updated automatically and therefore, if the process is set to start "when a record is created or edited" and the criteria on is met, the process will try to update the lead after being converted, which is not possible. 

 
ResolutionAn easy way to avoid this is adding a criteria to the process to check if lead.IsConverted is Equals False and only make updates when the lead is not being converted.

If the above don't solve this issue:

Thanks,

Thanks Raj, this is really useful. It looks like a 3rd party (managed package) is what's causing this to fail so I've logged a ticket with their support to see what happens. I've passed on your advice though, when they come back I'll be sure to mark this as best answer!
Thanks
Dan
