[Bug] When using graphman drop, an error occurred

Bug report

When I use graphman to drop a subgraph, an error occurs. I am using the official Docker to run Graph, Postgres, and IPFS. Where is config.toml located, or could you provide me with a simple and usable config.toml configuration?

Relevant log output

graphman --config config.toml drop QmQsjzz9ekX3ej7zTNYY1m37eotTTfcLKs4MpzRLnyKc3D
Error: Configuration error

Caused by:
    No such file or directory (os error 2)
