When I try to get a list of files I get a nil in response (Swift 5)
I have a simple method where I want to get a list of the user's files. I took the implementation of this method from your PhotoWatch example. I also added a print at each step to track each step. But when I try to get a response, I get a nil. What's wrong? This user definitely has files in his Dropbox.
I would be grateful for help.
You just need to create the ScopeRequest object before calling the authorizeFromControllerV2 method.
As for the error, make sure you're only calling the authorizeFromControllerV2 method once. In your screenshot, I see you're calling authorizeFromControllerV2, and then are also calling a method of your own called "openDropboxAutorization". Are you also calling an authorize method from inside "openDropboxAutorization" by any chance?

The response method is given both a "response" and "error" object. If "response" isn't set, you should check "error" to see what went wrong with the call.
I handled the error, the problem was with individual scopes. I have selected the options I want and now I get another error.
API auth error - {
".tag" = "missing_scope";
"required_scope" = "files.metadata.read";

The 'missing_scope' error indicates that while the app is permitted to use that scope, the particular access token you're using to make the API call does not have that scope granted. Adding a scope to your app via the App Console does not retroactively grant that scope to existing access tokens.
That being the case, to make any API calls that require that scope, you'll need to get a new access token with that scope.
