[jedipunkz]

Hi,

I am using this action and I would like to get Japanese response.
and I checked that PR: #430

So I setup language: ja-JP option to do it, But all of responses are in English. How can I resolve this issue?

Your screenshot shows that you are using the Pro version. The yaml config of GitHub actions does not apply for that as it's a completely different system.

Please choose the language option in the UI or use the config file that the pro version accepts.
