Mashup Exception Error: We reached the end of the buffer

DataPne — Wed, 16 Aug 2023 15:08:12 GMT

Trying to load data from an on premise MySql server via a gateway to a Fabric Warehouse but a lot of the write to table commands are failing with an error:

Mashup Exception Error Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: We reached the end of the buffer.

Anyone come accross this before?

Thanks a lot 🙂

Hi,

I was about to recommend one thread where I made some comments before, than I noticed there are many threads with this error message or similar and with different solutions. The one where I made some comments is (https://community.fabric.microsoft.com/t5/Dataflows/Gen2-Dataflow-Failed-to-insert-a-table/m-p/3372458) but if you search for MashupException you will find many more.

I believe one of them workarount the problem avoiding staging on the dataflow, but there are so many I didn't follow all the detaisl.

In summary, just highlighting this error is appearing a lot around here, with different causes.

Kind Regards,

Dennes
