Transaction does not have a valid commit version

Hello! We are struggling for ~ 1 year with this error in our code once we started to use versionstamps.

How is it possible to have successful transaction and don’t have commit version?

Is it possible that your transaction doesn’t have any mutations or write conflict ranges?foundationdb/ at 904a39e4739664524dbf0df4d4d478ae7ae9e622 · apple/foundationdb · GitHub

Thanks! It was just retried transactions while requesting version stamp values!
