PipelineException when running dataflow. CompressedDataSize exceeds!
Another day, and another strange message from PQ online. I was trying to refresh a PBI online dataflow, and received the following:
PipelineException: With compression algorithm the compressed data size in a packet exceeds the max ServiceBus limit: GatewayCompressor - CompressedDataSize (25906718) of a non-compressed packet exceeds the maximum payload size of 8500000 .
I'm not sure how to resolve this exactly. I was pulling a very large chunk of json, and trying to encode it in a dataflow-table for subsequent use in another table (a "computed entity"). However it appears that PQ is not willing or able to help me out.
Does anyone have any idea how to send a very large chuck of json out into this storage account where my dataflows live?
I wish this error message was more meaningful. Most people shouldn't have to know or care about "servicebus", nor should they worry about bumping into some random/arbitrary 8.5 MB payload maximum.
Any help would be appreciated. This error doesn't come up in any google searches related to Power BI.

While trying to fix this, I get another error with a similar format.
This time its complaining about uncompressed sizes.
PipelineException: The uncompressed data size specified in a packet header exceeds max limit: GatewayDecompressor - Header.UncompressedDataSize (193364724) of a compressed packet exceeds the maximum allowed uncompressed payload of 157286421 .
Gateways and APIs have payload size limits, AWS for instance
I think moving to Premium capacity could help you out.
We are already on premium.
I really wish dataflows were more user-friendly. There should be a way to serialize arbitrary objects out there, for the sake of related entities ("computed entities").
These CSV-compatibility requirements are just plain obnoxious. There should be a way to save XML, JSON, text, and lots more. Even binary formats like parquet would be very helpful!
