I'm not sure off hand what that error would indicate. (It's not an error from the Dropbox API itself.) Do you have a live sample page where I can plug in my own access token and test this out so I can take a look?

    GREG! Thank you so much for answering.

     

    Yes, just created a live page for you to test.

    It uses the exact same code I showed in my post, just substituted my access token with the input.

      Thanks! I just tried this out but I don't see the "ERR_INVALID_HANDLE" error you mentioned, when attempting to upload a file larger than 150 MB. What browser/version are you using?

       

      I do notice that you don't seem to be sending the session ID up properly on the /append_v2 calls. The parameters being sent look like:

      {"cursor": {"session_id": "undefined","offset":"8000000"},"close":false}

       

      So, it seems you have a bug when you get or set the session ID. You'll need to make sure you supply that session ID value (as returned by /start), not undefined.

        The ERR_INVALID_HANDLE comes from here, when you mouse over the Status column of the request. 

        I'm currently using Google Chrome - Version 89.0.4389.114 (Official Build) (64-bit)

         

        Thanks Greg! I'll go fix that right away. 

        However, would the incorrect session_id header explain the Start session failing as well?
