"No auth function available for given request" return on /token request

[jenseno]

Hi. I send the following form data with the code I got from the authorization page. I use redirect_uri back to my app through localhost.

However I get the following response (error code 400): "No auth function available for given request".

My request form data looks like this:

Header:

POST /oauth2/token HTTP/1.1
Host: api.dropboxapi.com
User-Agent: UnityPlayer/5.5.2f1 (UnityWebRequest/1.0, libcurl/7.46.0-DEV)
Accept: */*
Accept-Encoding: identity
X-Unity-Version: 5.5.2f1
Content-Length: 177

Post data:

code=KNJIALLS_WCAAAAAAABSTZP97AYWIZJPX9B1A6CBFUC&grant_type=authorization_code&client_id=<removed for security>&client_secret=<removed for security>&redirect_uri=http%3A%2F%2F127.0.0.1%3A6756

I could not find anything on google or the forums, so now I'm trying here.

I can see that auth authorization is missing (Authorization bearer) but the docs said nothing about this, and I don't have a token at this stage in the process anyway.

Thanks in advance

Any chance you'd had the time to look into this? I got everything else working for next release of my app 😉

This is open with the team, but I don't have an update on it yet. I'll follow up here once I do.

[jenseno]

Any news? I really need this to release next version of my app and dropbox backup is the number one requested feature from my costumers 😉

This is open with the team, but I don't have an update yet.

Can you check if you're still seeing this though? I don't know what the underlying cause was yet, but it may have just been a transient issue.

I still get the same error. If you guys have Unity installed, I can send you a sample project that produces the error?

[Greg-DB]

Sure, that may help us investigate. Thanks!

[jenseno]

Hi. I have the sample code ready. Where can I mail it securely? For your convenience, it contains my app secret keys etc.

Thanks! You don't need to include the app secret, but in any case you can submit it in an API ticket here:
