The one below happened when PB try to call Flow and it fail, it may be caused by the Flow is Inactive, while the one earlier is related to update record fail.

In our blog earlier, we mentioned that prefix 301 is InteractionDefinitionVersion, but we can't really easily see that record content by putting into URL, or by query with SOQL. So, how to trace that 301 error is referring to which Process Builder or Flow?

The user who create the Process Builder will get email from FlowApplication, with subject "Error Occurred During Flow "flow name", this email will mentioned the flow name, but no Version Id information as in the screenshot above. If the user create that Process Builder not in office, how you can trace Version Id prefix 301 is related to what?

There are 2 options to find this:

1. Flow
Use Flow Designer to check if that Id is refer to which Process Builder or Flow -- remember that Process Builder is using Flow as it engine. Follow this Url https://na3.salesforce.com/designer/designer.apexp#Id=30190000000XmQs, change na3 to your salesforce instance and you should see the Flow Name which is Lead Share for this sample.

2. Workbench
Login to workbench, navigate to menu Info | Metadata Types & Components, select Flow from drop down and click Expand All. You should find that 301 Version Id from the components and get the Flow name, which is "Lead Share"

This is the Process Builder as result of our finding:
