Is your feature request related to a problem? Please describe.
Seems to be no tests /checks present for this service ( is tested by overall integration tests only). I. e.there is no support to see if a dependabot update or other changes breaks this particular service before approving a PR .

Describe the solution you'd like
A mminimal set of tests for the proxy service that do not require a full blown stack to interact with. Build, ++
