incomplete_raw_credentials is thrown on slack user_token

Might be related to this one #3560

I want to obtain slack user token, not bot token

So when I trigger connection with the following code.

      const connectSession = await createConnectSession.mutateAsync({
        integrationId: selectedIntegration.id,
      });
      new Nango({
        connectSessionToken: connectSession.token,
      })
        .auth(
          selectedIntegration.id,
          selectedIntegration.provider.id === 'slack'
            ? {
                authorization_params: {
                  user_scope: // <---- supplying user scopes like this works
                    'channels:history,channels:read,channels:write,channels:write.topic,chat:write',
                },
                user_scope: [ // <---- supplying user scopes like this does not works
                  'channels:history',
                  'channels:read',
                  'channels:write',
                  'channels:write.topic',
                  'chat:write',
                ],
              }
            : {},
        )
        .then((_result) => {

  },
  "error": {
    "message": "An unhandled error of type 'incomplete_raw_credentials' with payload '{}' has occurred",
    "payload": {}
  }
}

I tracked the issue down to this line.

Seems like parseRawCredentials expects to find access_token at the root, but it's under authed_user, i.e. authed_user.access_token.
