TwitterAPIExchange：Chunk Media Upload：STATUS需要身份验证

Question

This self-contained, PHP, TwitterAPIExchange code attempts to upload a file file to Twitter using Chunks. It all seems to work except the STATUS part (you have to do INIT, APPEND, FINALIZE and can check its STATUS) returns

string(64) "{"errors":[{"code":32,"message":"Could not authenticate you."}]}" Response after check STATUS: end

This does not seen to affect the upload, but I do not understand why one of the four commands does not work? Any ideas/suggestions?

At the end of this post, I have included the output of this code snippet (note: APPEND does not return a response - this is correct accordinging to the API documentation, which shows the various responses and var_dump's of each of the commands.

As an aside the final tweet works but does not display the image, but this is an ongoing issue that I have sought help on elsewhere, but any insights to that would also be welcome.
