Hi Guys,

been using clearml-serving for several years now and recently upgraded to the new version of the app server and clearml-serving. However, when deploying models I'm now getting the following error:

HTTP/2 500 
date: Mon, 19 May 2025 22:27:39 GMT
content-type: application/json
content-length: 112
server: uvicorn

{"detail":"Error  [<class 'AttributeError'>] processing request: 'NoneType' object has no attribute 'base_url'"}

It looks like the helper doesn't have any base_url when trying to get the model inside the pod
