CREDENTIAL Overwrite with environment variables

[Martin_Forster]

Describe the problem/error/question

CREDENTIAL_OVERWRITE_DATA does not support a json array to overwrite more then one type.

What is the error message (if any)?

i solved it, in embed configuration api is a example how the variable must be set.
see
Configuration | n8n Docs

{
    "asanaOAuth2Api": {
        "clientId": "<id>",
        "clientSecret": "<secret>"
    },
    "githubOAuth2Api": {
        "clientId": "<id>",
        "clientSecret": "<secret>"
    }
}

this is my line in a docker compose file to set the variable.
- CREDENTIALS_OVERWRITE_DATA={"oAuth2Api":{"clientId":"<someclientid>","clientSecret":"<someclientsecret>"},"httpBasicAuth":{"user":"<someusername>","password":"<somepassword>"}}
