TypeError: cb.apply is not a function

Question

I\'m trying to run an existing React Native project that uses Metro Bundler. My operating system is Ubuntu 20.04 and I\'ve tried to run the app both on a physical Android device

Answer 1

I had a very similar problem on CI, but it works normally on my local machine (Node 13). In the CI, when building the project on CircleCI or on AppCenter with a code that I already released two months ago it throws the error below. It just does not make sense, it's like node had broken dynamically.

I tested the same code with node 10, 12 and 14, but now it works just with node 10 (10.22.0).

The error I had:

/home/circleci/my-app/node_modules/@react-native-community/cli/node_modules/graceful-fs/polyfills.js:285
        if (cb) cb.apply(this, arguments)
                   ^

TypeError: cb.apply is not a function
    at /home/circleci/my-app/node_modules/@react-native-community/cli/node_modules/graceful-fs/polyfills.js:285:20
    at FSReqCallback.oncomplete (fs.js:169:5)

> Task :app:bundleReleaseJsAndAssets FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:bundleReleaseJsAndAssets'.
> Process 'command 'node'' finished with non-zero exit value 1

UPDATE

What solved my problem was to add a resolution to the package.json to do not allow any lib to use a version of graceful-fs that is before "4.2.4". Now it works again with node 12.

PS: Don't forget to run yarn or npm run install to update your .lock. If this solution does not work for you, please add a comment to this thread related to this problem on Node 12.18.3
