Bug: declaring a config field with environment variable is not working

[outerlook]

Version / Commit

v0.7.3

Operating System

Ubuntu 22.04.4 LTS

Configuration

I'd like to configure just one field using env variables, in this case:

[chain.p2p]
external_address = <this one>

I used this env variable to configure it:

KWILD_CHAIN_P2P_EXTERNAL_ADDRESS=kwil-node-1:2656

Expected Behavior

I'd expect the config to be populated with the env string.

Actual Behavior

config is not picked up

Steps to Reproduce

1. setup any server with some custom value for KWILD_CHAIN_P2P_EXTERNAL_ADDRESS
2. in debug mode, put a breakpoint at https://github.com/kwilteam/kwil-db/blob/main/cmd/kwild/config/config.go#L346
3. see that the config didn't use it and envConfig is in an empty state.

3. see that the config didn't use it and envConfig is in an empty state.

Additional Information

Or did I pick something wrong from the docs? Not to be discarded 😅

Another note is that only one level of the configuration structure seems unmarshalled by viper.
It looks for KWILD_ROOTDIR, KWILD_APP, KWILD_CHAIN, and KWILD_LOG, then stops.

It is not urgent, as it has workarounds.
