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.

Is is possible for the test to update Go to a newer version?

Hey @Binh0723, looks like your repo is linked to the v1.24 buildpack. Could you try upgrading it?
