cvat: Could not get models from the server - Error: Request failed with status code 500.

My actions before raising this issue

• Read/searched the docs
• Searched past issues

Expected Behaviour

I was expecting to see a model that is currently running.

Current Behaviour

After deploying the TensorFlow model, when I go to http://localhost:8080/models I see the error message as below.

Could not get models from the server
Error: Request failed with status code 500.
"<h1>Server Error (500)</h1>".

Possible Solution

Still searching.
