Midnight Node with image 0.18.0-rc.7 and the environment is testnet-02 can't running

Did I run the configuration correctly? I'm running Midnight Node with image 0.18.0-rc.7 and the environment is testnet-02. I'm running it using the repository https://github.com/midnightntwrk/midnight-node-docker and I'm getting the following error:

thread 'main' panicked at node/src/cfg/mod.rs:346:37:
called `Result::unwrap()` on an `Err` value: ConfigError(Failed to load config testnet-02)

Read node/src/cfg/mod.rs around line 346 and inspect the midnight-node-docker container configuration for image 0.18.0-rc.7 and environment testnet-02. Reproduce the startup failure and determine whether the environment is supported and configured correctly; done means the node starts without the reported configuration error or the required configuration is documented.
