New participant for MVD - Fails during initilization of new participant company4

[MagicFeeling]

Hello all,
I am trying to add a new participant to the MVD which I called company4 which I copied from company3. I changed all files I could find where company3 is referenced but I get a NullPointerException at the file DecentralizedIdentiyServiceExtension.class at line 69 (Couldn't resolve private key) during Initialization. The container for compan4 exits with "dependency failed to start". Is there a recommended way of how to add a new participant to the MVD or was the MVD not intended for that purpose. It would be nice if someone could offer some direction as this project seems to be really amazing. You can find the output from the command docker compose -f system-tests/docker-compose.yml up --build:

The problem was that the .jks file needs to be opened with KeyStore Explorer and its name changed from company3 to company4 internally if copied from company3. The password for the .jks file is documented in the Readme.
