Dataflow Error: The current row is too large to write

Hi all,

Currently getting this error when trying to publish a Gen2 Dataflow:

Mashup Exception Error Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: The current row is too large to write

Filtered the dataset down to one row for testing but still getting this error - any tips?

Thanks a lot 🙂

Hi Miguel 🙂 

We are indeed using a gateway, I just updated it to the newest version but now I am getting:

Error Code: Mashup Exception Error, Error Details: Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: Evaluation resulted in a stack overflow and cannot continue.

Memory issue I guess although there is not much data, and using a pretty expensive version of Fabric.
At least a new error, although they seem never ending.

Could you please raise a support ticket so an engineer can look deeper into this?

Hi!

Are you using a gateway? if yes, what version of the gateway are you using?

There was a recent change at the service level and also the gateway which should clarify things for prior cases that would arise this error. Please try to refresh your dataflow again, with the latest version of the gateway if needed, and let us know if it succeeds or if you're receiving a new error message.
