Unable to get edc-example working.

Hi, I am trying to test the edc-example, but it does not work for me.

Some remarks about what I found out. Both about the example, as well as about the pull-request and subsequent merge:

• I noticed the add-authorization-header branch was not deleted yet. After merging a pull request, you can click the Delete branch button and it will remove the corresponding branch. This way the repository will not contain many old branches.👍
• It seems like something went wrong with merging, since the code still mentions the edc.properties file, while I think we have replaced it with the regular knowledge engine configuration.
• The README.md file of the edc-example mentions the testsc:1.3.3-SNAPSHOT, but that was only necessary before we merged to the master. Now that the EDC functionality is in the master (and in next release) we can most probably just use ghcr.io/tno/knowledge-engine/smart-connector:1.3.3-SNAPSHOT and after release ghcr.io/tno/knowledge-engine/smart-connector:1.3.3.
• When runtime-1 tries to contact runtime-2 with a token, this fails with the Failed to send message e8a6b900-fc72-49c2-9230-76b9dfbd796f to http://runtime-2:8081, got response 403: Invalid authorization token message. Not exactly sure why, but it might have to do with the missing edc.properties file.

Can you check whether you can get it working?

Got one step further in checking what goes wrong and it might be caused by the fact that the ke.edc.token.validation.endpoint configuration property is never used in the knowledge-engine codebase. Therefore the received token from another runtime is always invalid and no messsages are being accepted causing the http status 403 message mentioned above.

Below the runtime-1 and runtime-2 log from the edc-example:
