My file (.csv) is 2.58MB and I continue to receive the 400 error. Isn't the file limit 100MB? The total lines in this file is 17,155. If I reduce my file size below 2.5MB then the file uploads successfully.
If the file is uploaded via the git package on my linux terminal the commit is also successful. It seems the issue is only with the browser upload of the file.
What could be causing this failure if I have not reached the file size limit?
