Attaching images does not work as expected about ringcentral-extensible

[alexbegt]

Additionally, the updateUserProfileImage endpoint does not like when the requests.json is sent to it along with the image, if this is provided to the endpoint it throws back ACT-331 (Profile Image not valid).

Sorry for the late reply. Next time please create a ticket here to get timely response: https://developers.ringcentral.com/support/create-case

I am totally unaware of such an issue. Yes something is hard-coded, but all the test cases still pass. And as far as I can tell, server side doesn't care about the name "attachment", it cares about the filename instead.

Are you sure that "updating a profile picture" stops working? Let me check.

Update: I have reproduced the issue.

It seems that profile image uploading is the only place that is broken.
I tried IVR audio and also fax sending, both worked.
My goal was not to provide a general purpose form-data implementation. I just wanted to cover all RingCentral use cases.
But I didn't test profile image.
