Resumeable google-photos-api final call returns "not a multiple of the 262144 byte chunk granularity."

Question

I am following the information on uploading large files to Google Photos here - https://developers.google.com/photos/library/guides/resumable-uploads

I am using the pattern described here - https://github.com/tanaikech/Resumable_Upload_For_WebApps/blob/master/index.html

Everything goes OK until the last chunk upload which has a return status of 400 and message "The client sent 259638 bytes, which is not a multiple of the 262144 byte chunk granularity."

As this is the last chunk it of course is not 262144 in length. The doco says to use X-Goog-Upload-Command: Set to upload. For the last chunk, set to upload, finalize

It seems to be ignored.

Any suggestions?

Ok, so after checking the header on the last call it was clear I wasn't setting the header correctly X-Goog-Upload-Command: upload, finalize Fixed the test to check if reached last call and now setting header correctly and all is good
