Maybe it’s too defensive to do this, but perhaps we should check that C3_DEFAULTS.lang is actually in supportedLanguages? Other than thjis I’m happy to approve

Thanks, done. How about now?

Error: src/index.ts(5,27): error TS2339: Property 'MY_TEXT' does not exist on type 'Env'.

I guess the type check failure is not related to my change.
