Context Information

Used version

• edc: ghcr.io/sovity/edc-ce-mds:latest
• edc-ui: ghcr.io/sovity/edc-ui:2.1.0

Logs:

[tmberthold]

The "Client unknown" error message in response from the MDS DAPS in the test environment indicates that the MDS Test-DAPS does not know the connector. So the MDS test DAPS does not issue a token.

Have you followed the steps described in the MDS Wiki, i.e. how to:

• get a certificate for the respective environment https://github.com/Mobility-Data-Space/mobility-data-space/wiki/1.-Step-(Connector-Certificate)
• set up a sovity EDC CE v4.2.1 for access https://github.com/Mobility-Data-Space/mobility-data-space/wiki/2.-Step-(Configuration)

The current version edc-ce-mds:latest (6.0.0 at the time of writing) used in docker-compose is definitely not the right one for the current MDS environment, please use v4.2.1 as described in the wiki.

In addition, I would recommend not using quotation marks for the EDC_OAUTH_CLIENT_ID, for example, as in case of doubt they could be interpreted by the EDC as part of the ID.

Thank you very much for the clarification!
