There seems to be an authentication that might randomly happen the first time the app links to dropbox. (it happened in 2 out of 6 tries). However it seems to work correctly if the app is restarted.
The flow is, Link to dropbox, when successful and when the focus returns to my app, i try uploading a file, then I get the following error:
2015-10-16 19:29:50.499 appName[300:29495] [WARNING] DropboxSDK: error making request to /1/files_put/auto/Backup (2015-10-16 at 1929).zip - (401) Authentication failed
2015-10-16 19:29:50.499 appName[300:29495] File upload failed with error: Error Domain=dropbox.com Code=401 "(null)" UserInfo={sourcePath=/private/var/mobile/Containers/Data/Application/9357CDDE-0F42-4AE5-B5AD-7151BA370FC5/tmp/Backup (2015-10-16 at 1929).zip, destinationPath=/Backup (2015-10-16 at 1929).zip, error=Authentication failed}
2015-10-16 19:29:50.500 appName[300:29495] File upload failed with error (localized): The operation couldn’t be completed. (dropbox.com error 401.)
Also if i try requesting metadata i get this error:
2015-10-16 19:29:59.107 appName[300:29495] [WARNING] DropboxSDK: error making request to /1/metadata/auto - (400) invalid_request
2015-10-16 19:29:59.108 appName[300:29495] Error loading metadata: Error Domain=dropbox.com Code=400 "(null)" UserInfo={error_description=No auth function available for given request, path=/, error=invalid_request}
-------------------
However this is strange because it should ALREADY be linked, since i check it before performing the requests like this:
if (![[DBSession sharedSession] isLinked]) {
return;
}
By the way, i followed everything written on this guide: https://www.dropbox.com/developers-v1/core/start/ios
And as mentioned earlier, the weird thing is that, it might or might not happen the first time it is linked. So its kind of ****** to replicate. Last time it happened, i closed the app, re-opened and it was suddenly fixed.
