500 Internal Server Error when updating file with 40MB data #update-a-file

The update(PUT) API call for file sizes under **22MB** works through. But for bigger file sizes (such a **40MB**), the update rest endpoint of Github fails with a **500 internal server exception.**

Not sure whats happening here. Size of the test file is greater than 10 megs, so hosted payload could be found here : https://nofile.io/f/0gampnACOOE/testAPILargeFile_base64.txt

Reproduce the update (PUT) API call with files below and above the reported 22MB threshold, using the linked 40MB base64 payload as a reference. Inspect how the GitHub API wrapper handles large update requests; done means the behavior is understood and the 500 error is either resolved or clearly identified as an API limitation.
