That's a shame though overall I think it's being improved so good to stay up-to-date. Looks like a lot of the e2e tests are affected for some reason

Might be fixed now.

thx! The last failed e2e test should be fixed in new base branch

[tzemanovic]

@tzemanovic Done

[tzemanovic]

I'll rebase onto latest base branch and add it a new draft

I'm having some trouble with this in #1603 draft. There's a failing e2e test in CI, but when I try to run it locally it fails for me earlier than that at the command namadac init-validator --alias new-validator --source Bertha --unsafe-dont-encrypt --gas-amount 0 --gas-limit 0 --gas-token NAM --commission-rate 0.05 --max-commission-rate-change 0.01 --node 127.0.0.1:26657. It panics with:

The application panicked (crashed).
Message:  Mismatch between definition and access of `chain-id`. Unknown argument or group id.  Make sure you are using the argument id and not the short or long flags

I'm having some trouble with this in #1603 draft.

Ah so it's not just draft, I'm also have the same problem on this branch

[tzemanovic]

The problem was a missing arg definition for chain-id arg in Tx. It was introduced in merge of #925 but previous clap version wasn't able to detect it.

Clap only does the detection in debug build (when debug_assertions is enabled - https://github.com/clap-rs/clap/blob/master/clap_builder/src/parser/matches/arg_matches.rs#L115) so we're not catching these in CI that uses release build. I've opened #1610 to enable debug_assertions in the CI e2e tests.

Great that you found it!
