Unable to Install the Plugin Cairn

I am trying to embed tutor plugin cairn in my edx server.
I have followed the instructions on the github repo

On the final step tutor local launch the process fails and is exited. I am receiving this error bellow.

2024-10-07 07:31:55,944:ERROR:flask_appbuilder.security.sqla.manager:DB Creation and initialization failed: (psycopg2.OperationalError) connection to server at "cairn-postgresql" (172.18.0.9), port 5432 failed: FATAL:  password authentication failed for user "superset"

When I look at the config file nano /root/.local/share/tutor/config.yml I have following password/secrets available

  1. CAIRN_CLICKHOUSE_PASSWORD
  2. CAIRN_POSTGRESQL_PASSWORD
  3. CAIRN_SSO_CLIENT_SECRET
  4. CAIRN_SUPERSET_SECRET_KEY

In the postgres docker instance, I did
image
and superset is not displayed

Your guidance is appreciated.
Thanks in advance!
