500 error with update_with_media

[Cipherlad]

I’ve been struggling with this for a while, and cannot figure out why my request returns a 500 error.

POST https://api.twitter.com/1.1/statuses/update_with_media.json HTTP/1.1
Authorization: OAuth oauth_consumer_key="...", oauth_nonce="...", oauth_signature="...", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1364272000", oauth_token="...", oauth_version="1.0"

Just a test post!

Content-Disposition: form-data; name="media[]"; filename="my_image.jpg"

… followed by the binary data for the image being posted. According to your examples I don’t see a thing wrong.

I think your request is a bit off. It looks like you have an extra boundary line between the media[] headers and the image data. You also have an extra space between headers in the first and third blocks. Finally, there are two Content-Type headers in the first block.

Here’s a request which succeeded:

I should follow up and say that the end of the request looks like this:
