Common Errors

Config file mounting (EISDIR | invalid mode: RO)


One of the following errors are logged during the startup of the connector:

  • Error parsing your configuration file: [/config.json]: EISDIR: illegal operation on a directory, read
  • ERROR: for connector Cannot create container for service connector: invalid mode: RO

How to fix?

Given the following filesystem structure:

└── connector/
    ├── config.json
    └── docker-compose.yml

If you mount /home/connector:/config.json:RO, the created /config.json in the container will be a directory. To fix this the mount has to be /home/connector/config.json:/config.json:RO or ./config.json:/config.json:RO (docker compose translates relative links to absolute links).
