I’m using a function Go in the sync.WaitGroup which was introduced in version 1.25 and it seems that the tester still using the old version and can not compile my code.

Hey @Binh0723, looks like your repo is linked to the v1.24 buildpack. Could you try [upgrading it](https://forum.codecrafters.io/t/new-feature-update-language-version/15245)?
