Babel_traverse: A type predicate's type must be assignable to its parameter's type

I'm running into the problem mentioned in the title with my Nest.JS project. It appeared after one small commit (nothing special, just updates return types in methods), but when I rolled back all changes it is still remaining. I can't figure out where I have to dig to fix this issue. Also the issue appears only during docker compose build at nest build command. Locally all works perfect: build, debug, start commands work as expected. Full error log:

Solution

  • Using version 7.21.0 on @babel/core devDependency worked just right for me. Mind the version without ^. In case you are using only @babel/traverse try an older version too.
