Dropbox API problem

Thanks! It looks like the error message is:

"Bad state: Cannot set the body fields of a Request with content-type "application/octet-stream"."

That's not an error message from the Dropbox API itself. It appears to be an error message from the HTTP client you're using. It looks like the problem is that you're attempting to set the "body" parameter to be a Map value, which isn't supported in this case.

When uploading to Dropbox via an upload API endpoint, the request body should contain the file data. In your code you're attempting to set it to a Map contain the API parameters, which wouldn't work anyway.

You should update your code to send the file data in the request body, and set the API parameters for the API call in a "Dropbox-API-Arg" request header, which would be in the "requestHeaders" variable you currently have (like the commented out line).
