Hi Erik, Thank you for your response! After I read your email, the first thing I tried was to remove the CRLF before the first boundary. I must admit I didn't believe it would help, but it seems it was the problem. Removing it made the request pass, in both the example I posted (ran in QConsole) and in a totally separate example written for Node.
So to the REST API devs... I am not an expert in the HTTP grammar (like if if anyone could claim so), but it looks to me the CRLF should be ignored as part of the preamble. In any case, the 500 could be avoided (either to ignore the CRLF or to return a 400 instead with a meaningful message). But as far as I am concerned, problem solved ;-) Thank you, Erik!
