kubeflow models web app does not display models when getting inference services

The kubeflow models web app (v0.6.0) does not display models although it gets a 200 response for /models/api/namespaces/namespace/inferenceservices

The models web app displays a 502[undefined] error few seconds after loading but there are no errors in the pod log and the infereneservices endpoint returns 200 as mentioned above:

I inspected the frontend with the developer tool and found this error:

main-es2015.397fc6f1309ed2bc2341.js:2 ERROR TypeError: Cannot read properties of null (reading 'runtimeVersion')

I think this is the same issue as #1

@amybachir

That looks like the same issue as you said.
It occurs when you have a custom predictor

It should be fixed when this PR is merged #7
