Power BI report failed to refresh on web but refreshes in Desktop ver

[Sora]

I had no issue with this report before, but today when the scheduled refresh failed, also fails when I manually refresh it from the online workspace.

However I had no issue doing data refresh in the desktop version.

Below is the error message.

{"error":{"code":"DM_GWPipeline_Gateway_CompressedDataSizeForPacketExceededError","pbi.error":{"code":"DM_GWPipeline_Gateway_CompressedDataSizeForPacketExceededError","parameters":{},"details":[],"exceptionCulprit":1}}} Table: Downtime_filename_info.

I tried re-publishing it and it still fails refreshing on the web.

Hi @Sora ,
Based on your description and the error code provided, the problem appears to be related to the size of the data processed during the refresh operation exceeding the allowable limit for a single packet passing through the local data gateway.
I checked the documentation, which indicates that the exact limit is 10 GB of uncompressed data per table.If you are experiencing this issue, there are good ways to optimize and avoid it. In particular, reduce the use of highly constant long string values in favor of normalized keys. Or, if columns are not used, removing them can help.
Of course, you can also try to configure incremental refresh for that dataset to avoid the data overload issue.

Hello @Sora ,

in power bi desktop go to power query and try refreshing this table "Downtime_filename_info." from power query.
