beacond comet show-validator is broken

[chuck-bear]

beacond comet show-validator is broken since maybe alpha.5.

How to reproduce?

In the main branch, run:

make build
build/bin/beacond comet show-validator

Output:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x48 pc=0x10162a2a0]

What should be the output here?

{"type":"cometbft/PubKeyBls12_381","value":"ghfsdgfjsdfgjasghjsfahgjsdfghj"}

This is basically the pub_key part in the priv_validator_key.json.

The bet-cli has an example of "fix".

@chuck-bear thanks for filing the issue.
I don't know what the bet-cli is.
I don't have a solution yet, but I have been able to repro the issue and can provide some preliminary details.
Crash is due to nil pointer exception. We are not specifying a codec for the command at hand.
For context see difference among:

• current codebase

  beacon-kit/mod/cli/pkg/components/client_context.go

  Line 47 in 66bad3e

  clientCtx := client.Context{}.

• v4 codebase

  beacon-kit/mod/cli/pkg/components/client_context.go

  Line 57 in dd2155c

  clientCtx := client.Context{}.

The missing bit is figuring out how to duly initialize the codec so that it can work with currently used types.
