Missing Documentation for API_KEY_ENABLED Configuration in Identus Cloud Agent

[Neethu-Muthu]

Is this a regression?

No

Description

When using the Identus Cloud Agent, I encountered the following error while trying to interact with the Cloud Agent API:
{
"status": 403,
"type": "authentication_error",
"title": "",
"detail": "ApiKey key is not provided",
"instance": "error:instance:9912cec4-df07-4b62-ba7c-2ffd6b9609cf"
}
The issue occurs because the API_KEY_ENABLED environment variable is set to true by default in the Docker Compose configuration. This critical detail is not mentioned in the repository’s README.md file or related documentation, leaving users unaware of how to disable this feature if not needed.

To resolve this issue, I propose updating the README.md file to include a Troubleshooting section. This section should explain how to locate and modify the API_KEY_ENABLED variable in the docker-compose.yml file and restart the services.

Please provide the exception or error you saw

curl --location \
--request POST 'http://localhost:8000/cloud-agent/did-registrar/dids' \
--header 'Accept: application/json' \
--data-raw '{

        },
        {
          "id": "issue-1",
              "purpose": "assertionMethod"
        }
      ],
      "services": []
    }
}'
{"status":403,"type":"authentication_error","title":"","detail":"ApiKey key is not provided","instance":"error:instance:9912cec4-df07-4b62-ba7c-2ffd6b9609cf"}

Please provide the environment you discovered this bug in

Operating System: Ubuntu 22.04.3 LTS
Docker Version: version 27.0.3, build 7d4bcd8
Docker Compose Version: docker-compose version 1.28.5, build c4eb3a1f
Identus Cloud Agent Version: 1.36.1

Anything else?

To help other users troubleshoot similar issues, I recommend including the following instructions in the README.md file:

Locate the Docker Compose File:
Navigate to infrastructure/shared/docker-compose.

Modify the Environment Variable:
Change API_KEY_ENABLED=true to API_KEY_ENABLED=false in the docker-compose files to disable the API key authentication mechanism.

Restart Services and Verify Changes:
Re-run your API commands to confirm the error is resolved.
