Use docker or podman to test this pull request locally.

Run test server using develop.opencast.org as backend:

podman run --rm -it -p 127.0.0.1:3000:3000 ghcr.io/opencast/opencast-admin-interface:pr-522

Specify a different backend like stable.opencast.org:

podman run --rm -it -p 127.0.0.1:3000:3000 -e PROXY_TARGET=https://stable.opencast.org ghcr.io/opencast/opencast-admin-interface:pr-522

It may take a few seconds for the interface to spin up.
It will then be available at http://127.0.0.1:3000.
For more options you can pass on to the proxy, take a look at the README.md.

@JulianKniephoff do we also need to fix this in src/components/shared/wizard/WizardStepperEvent.tsx ?

[JulianKniephoff]

Here I was naively thinking that we would properly reuse code somewhere ...

[ziegenberg]

I just checked, and this is fixed for creating a new series but not for creating new events.

Sadly, WizardStepperEvent.tsx and WizardStepper.tsx do not share any code, though they probably should.

Works now! :)
