ReportGenerator 5.1.18 fails with reading historic reports

[lvanzijl]

Since upgrading to 5.1.18 I am not able to use the reportgenerator anymore. Previous version was 5.1.17 which ran successful a week before.

So you have enough information in the logging below or do you require more details? (I anonymized namespaces a bit in the log)

This issue is not related to version 5.1.18. Somehow your code base contains a class where AssemblyName + Classname is no longer unique.

Version 5.1.19 should fix this issue. Could you please try again? New release should be available in a few minutes.

Thanks for the quick fix ! When I encountered this bug I looked through the changesets but couldnt find anything even remotely close to that namespace, but if it's fixed now that doesnt really matter :).

I have to wait for our onprem azure devops to run the update extensions task to get the new version, I hope to be able to test the new version tomorrow (gmt+1).

While I was typing this the extension was updated, Its fixed now thanks!
