Dynamics 365 : Unrecognized Guid format

Recently, my client hit an error while opening a record, the form doesn't rendered anything, it totally a blank page.

After turn on the tracing, the log file show us a very weird error message "Unrecognized Guid format".

we search through everything, but unfortunately those solution didn't help us.

After that, we found out the similarity between the records, it is under a deactivated Business process flow. We tried to reactivated it, but it thrown us an error message.

It seems that there is something wrong with the BPF. So we decided to investigate deeply.

One of the step is missing, it became "Record" instead of the field we selected before. So after we choose back the correct field and save. The User is able to Open the record again.

Solution

- Remove the "Record field" or Choose a correct field.


I hope this will save you some time and Happy 365-ing.
