Hi @rlucke
Thank you for contributing to the Opencast Editor.
We noticed that you have not yet filed an Individual Contributor License Agreement. Doing that (once) helps us to ensure that Opencast stays free for all. If you make your contribution on behalf of an institution, you might also want to file a Corporate Contributor License Agreement (giving you as individual contributor a bit more security as well). It can take a while for this bot to find out about new filings, so if you just filed one or both of the above do not worry about this message!
Please let us know if you have any questions regarding the CLA.

EDIT(@lkiesow): The ICLA has been filed. Thanks. It may take some time for Apereo to process the ICLA. Feel free to ignore this complaint for now and point others to this comment if anyone asks.

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-645

For more options you can pass on to the proxy, take a look at the README.md.

Hi @rlucke,
can you please give your pull requests a title and a short description which explains what they do? Not having that makes it really hard to search for issues, makes quickly finding out what a pull request is about harder, and is annoying if you want to do a review since the linked issues don't necessarily explain the way you fixed an issue.

Can someone explain to me why Check ICLA goes wrong?

It might take sometimes (up to 1 day) for the record to be added into relative tables!
