an wrong in dropbox api v2 document curl -X POST https://content.dropboxapi.com/2/files/upload \ --header "Authorization: Bearer " \ --header "Dropbox-API-Arg: {\"path\": \"/Homework/math/Matrices.txt\",\"mode\": \"add\",\"autorename\": true,\"mute\": false}" \ --header "Content-Type: application/octet-stream" \ --data-binary @local_file.png when i set header --header "Content-Type: application/octet-stream" \ => can't send/ return error but when i remove that header and add --header "Content-Type: text/plain; charset=dropbox-cors-hack" \ => return 200, succeed, recheck: file was upload successful

I'm getting the same error message Expecting one of "application/octet-stream", "text/plain; charset=dropbox-cors-hack".

When you say you "can't send/ return error", what's the error you get exactly?

Content-Type: application/octet-stream Error in call to API function "files/upload": Bad HTTP "Content-Type" header: "application/octet-stream; Charset=UTF-8". Expecting one of "application/octet-stream", "text/plain; charset=dropbox-cors-hack". Error:400" It seems that orther dev of dropbox fix it? (Edit: i think my code error when not send data in binary)at that time the error return say Expecting one of "application/octet-stream", "text/plain; charset=utf-8"and when add two header Content-Type: application/octet-stream (1)Content-Type: text/plain; charset=dropbox-cors-hack (2)=> return erroradd only (1) or (2) => return success

Are you by any chance making an AJAX request and using Firefox? There seems to be a known issue with Firefox where it adds the "charset=UTF-8".

Sorry, i think my code error when not read file in binary mode -> server think a text -> return error utf-8

Content-Type: application/octet-stream

Error in call to API function "files/upload": Bad HTTP "Content-Type" header: "application/octet-stream; Charset=UTF-8". Expecting one of "application/octet-stream", "text/plain; charset=dropbox-cors-hack".

Error:400"

It seems that orther dev of dropbox fix it? (Edit: i think my code error when not send data in binary)
at that time the error return say
Expecting one of "application/octet-stream", "text/plain; charset=utf-8"

and when add two header
Content-Type: application/octet-stream (1)
Content-Type: text/plain; charset=dropbox-cors-hack (2)
=> return error

add only (1) or (2) => return success

I'm having trouble following this thread.

Is your issue resolved? Or are you still having a problem?

Was there a resolution to this? It looks like there's only 2 content-types I can send via the upload endpoint

Hi Hinto, we haven't heard back from Trương on this thread, so we don't know if their issue was resolved.

Fernando opened a thread here:

If neither of these help in your case, please open a new thread with the details of the issue you're having so we can help.
