Openemr 5.0.2 API authentication

I am trying to get an auth token with:

curl -X POST -H 'Content-Type: application/json' 'http://<<IP ADDRESS>>/openemr/apis/api/auth' \
-d '{
    "grant_type":"password",
    "username": "user",
    "password": "pass",
    "scope":"default"
}'

With my credentials and getting the following error:

<h1>Internal Server Error</h1>
<p>The server encountered an internal error or
misconfiguration and was unable to complete
your request.</p>
<p>Please contact the server administrator at 
 webmaster@localhost to inform them of the time this error occurred,
 and the actions you performed just before this error.</p>
<p>More information about this error may be available
in the server error log.</p>

When I check the apache error logs I don’t see anything except for PHP. Notice Is there something I’m missing?
