Answer 1

Hi
This may not be the answer but it's worth making sure your script is using windows line breaks (CR+LF). The page APIs are very sensitive about this and it always catches me out on a Linux based system.

Answer 2

Curious if the line breaks were the issue for the multipart payload being malformed?

There is one other problem with the request you have posted. In your commands JSON, the content should not be empty. It should look something like this:

[{'target':'body','action':'append','content':''}]

Otherwise you'll get an error 400 Bad Request with message=The PATCH argument $content: is invalid.
