react-native-safe-area-context: Property specifiers expected type of array but got null

I launch application one day and got this error while bundling:

[Fri Jun 11 2021 11:45:38.105]  BUNDLE  ./index.android.js 

error: node_modules/react-native-safe-area-context/src/SafeArea.types.ts: /home/gnome/src/urbest/z-frontend/node_modules/react-native-safe-area-context/src/SafeArea.types.ts: Property specifiers expected type of array but got null

I can’t determinate what went wrong. May be I change something in usage of SafeAreaView so it got null where should be array or something else.

I solved it by removing yarn.lock and package-lock.json and then running yarn install

Babel maintainer here. Does anyone have a complete stack trace or a repository I can clone and run a build command to reproduce the error?

I had two entries for @babel/types in my yarn.lock file which resolved to 7.6.1 and 7.15.0. Instead of manually modifying my lock file, I ran npx yarn-deduplicate to handle the multiple entries. Afterward the only entry was for 7.15.0 which resolved this error.

Thanks, I’m trying to reproduce the bug using that stack trace 👍

This seems to be a Babel bug, not caused by this project.
