data-connector-agent errors

Hello there.

Having an issue understanding why the "data-connector-agent" is only logging errors.

I used this docker-compose :

```
version: "3.6"

services:

postgres:
image: postgres:15
restart: always
volumes:
- db_data:/var/lib/postgresql/data
environment:
POSTGRES_PASSWORD: ***

graphql-engine:
image: hasura/graphql-engine:v2.28.0
restart: always
environment:
## postgres database to store Hasura metadata
HASURA_GRAPHQL_METADATA_DATABASE_URL: postgres://postgres:***@postgres:5432/postgres
## this env var can be used to add the above postgres database to Hasura as a data source. this can be removed/updated based on your needs
PG_DATABASE_URL: postgres://postgres:***@postgres:5432/postgres
## enable the console served by server
HASURA_GRAPHQL_ENABLE_CONSOLE: "true" # set to "false" to disable console
## enable debugging mode. It is recommended to disable this in production
HASURA_GRAPHQL_DEV_MODE: "true"
HASURA_GRAPHQL_ENABLED_LOG_TYPES: startup, http-log, webhook-log, websocket-log, query-log
## uncomment next line to run console offline (i.e load console assets from server instead of CDN)
# HASURA_GRAPHQL_CONSOLE_ASSETS_DIR: /srv/console-assets
## uncomment next line to set an admin secret

What might be the issue?
What is supposed to be at 127.0.0.1:4317?
