OJS3 Users API Issue

Hi,

I have been trying to use the OJS3 API and was going to use the users/{userId} endpoint to get some information about the user. When I went to this endpoint, it gave me the following error:

Slim Application Error

A website error has occurred. Sorry for the temporary inconvenience.

Is this a known issue? I tried searching for this issue, but I did not see it reported. Is there a fix that I could apply to my instance to get this endpoint working? Thanks in advance for the help.

Best,
Antelmo
