DataFormat.Error: We reached the end of the buffer.
I have a report that is set to refresh daily, where it adds 1MM+ rows of JSON data (about 85K rows of data after formatting to table) daily. When I set my date range in the body of my request to greater than two days and try to refresh on PowerBI Desktop, I get the following error message:
"DataFormat.Error: We reached the end of the buffer."
When I reduce the date range to two days or less (about 2.5MM rows in the JSON response/about 170K rows of tabular data), it runs fine, which tells me it's an issue with size. Does anybody know a solution to this or a workaround?
Thanks.
1. Try reinstall desktop, which has worked for someone who had the same issue.
2. Try change max cache size in the option. It looks a memory issue.

brianAtSapient - Are you using the 32-bit or 64-bit client? ImkeF - Any additional ideas other than client version and reducint the amount of data/columns coming across?
I'm running 64-bit client and have recently updated my PowerBI desktop to July 2020.
