Problem start container geopython/pycsw:latest with postgresql and materialized view

[espdits]

I create docker compose and i modified the config file:

  pycsw:
    depends_on:
      - pgstac
    container_name: pycsw
    image: geopython/pycsw:latest
    environment:
        PYCSW_SERVER_URL: http://localhost:8888
        PYCSW_CONFIG: /etc/pycsw/default.yml
    ports:
      - "8888:8000"
      - "5678:5678"
    volumes:
      - ./pycsw/default.yml:/etc/pycsw/default.yml
      - ./pycsw/mappings.py:/etc/pycsw/mappings.py

with default.yml:

i created my materialized view with this script:

from postgis.pgstac.items i 
JOIN postgis.pgstac.collections c ON i.collection = c.id

why i have this error?

I'm going crazy

[tomkralidis]

SQLAlchemy mentions issues with finding a primary key. In psql, what does a \dt <table> display?
