I'm using Moodle 3.1+, but when attempting to grade assignments, the following error occurs:
Invalid response value detected
File: .../lib/externallib.php
Line: 424
user => Invalid response value detected: username => Invalid response value detected: Invalid external api response: the value is "S000409", the server was expecting "username" typeError code: invalidresponse
Does anyone know why this might be occurring and how to fix it? Thank you
I found something very similar to this just last week. Here's the bug report - MDL-55371
In summary, some role overrides had been put in place in the affected courses. It was causing the web services code (which is used by the Javascript that generates the marking page) to miss information that the caused its own verification to fail.
If this isn't exactly the problem I think it may be something closely related.
Ran into the same issue on our Moodle 3.1 just now. We had to set the following capability from Not set to Allow:
View user profiles (moodle/user:viewdetails)
It doesn't like capital letters, make usernames lowercase.
So the question really is: does anyone actually know what is causing the issue? What the issue actually is? Is there a solution? Has it been fixed?
Has anyone got a solution, I've no capital letters in the usernames and I've changed the permissions of the roles to "allow" view user details as mentioned above for both the student and teacher role but I still have the error. Any advice would be really appreciated.
Kind regards
Mark
Has anyone has the solution/update in this case? I also always see "Invalid response value detected" when try to open the submission in the document viewer.
I've set the moodle/user:viewdetails to allow as well.
It happens in some courses but some courses don't. So, I cannot see the reason. Any help would be appreciated!
Thanks!
