DataMart: An internal error happened due to failed runtime assertion

[MarkPBI]

All of a sudden I can't make any edits to my DataMart...

I'm getting this error:

InternalError

• ErrorMessageAn internal error happened due to failed runtime assertion: Parameter 'transactionId' is not expected to be null..
• HttpStatusCode500

I'm trying to revert back to my previous situation, but nothing is working and it won't refresh.'

Hi @MarkPBI ,

We have seen on the internal platform that other engineers have reported this issue and submitted it.
The engineers on the product team are now aware and will do their best to resolve the issue. I will update here if there is any progress, so please be patient.

Best regards.

Hi Community Support,

was this problem solved? I am getting exactly the same error each time I try to add data to my Datamart.

Thanks!
