Status 400 response on swagger-ui redirect

[calohmn]

I have been testing the hawBbit helm chart PR eclipse/packages#549, using hawkBit 0.5.0.
When I add a local port-forwarding for the port 8080 of the eclipse-hawkbit pod (using the hawkbit/hawkbit-update-server:0.5.0-mysql image) and then make an HTTP request to the root resource, I get a 400 'Bad request' error.

The first response there is a redirect to /swagger-ui/index.html;jsessionid=<id>?attribute=redirectWithRedirectView and for that URL, there is the status 400 error.

Example (using local port 18080 forwarded to the pod port 8080):

$ curl --location -v http://localhost:18080

Accessing the root resource in a new incognito browser tab returns

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Bad Request, status=400).

(see also #1822).

Directly accessing http://localhost:18080/swagger-ui/index.html gives a status 200 response.
