Error occurs while running any gradle command lik for example ./gradlew clean or ./graldew assembleDebug

Reproducible Demo

1. Upgrade project libraries and react-native from 0.57.8 to 0.60.4 and use migration to androidX
2. Run any gradle command

Same error i am getting

[N1ghtly]

Same error here. Happens when I try to exclude a dependency from autolinking.

This is my react-native.config.js:

module.exports = {
  dependencies: {
    'react-native-background-location': {
      platforms: {
        android: null, // disable Android platform, other platforms will still autolink
      },
    },
  },
}

@N1ghtly
Removing that file fixes my problem yes... That is weird, but thank you
I'll be removing my react-native.config.js
Until I find out more.

[N1ghtly]

Unfortunately I can't remove that file because i need that module to be excluded from autolinking...

[thecodrr]

This needs to be investigated. This seems to be a problem with parsing react-native.config.js. I will take a look.

[affanhashone]

Just check do you have any empty space in dependencies, I was having empty space. now it works

[thymikee]

Just check do you have any empty space in dependencies

@affanhashone what do you mean by that?

[stevelacy]

I edited the file directly in node_modules and added && everywhere there could be an or Array.length call:

node_modules/@react-native-community/cli/build/commands/config/config.js

function isValidRNDependency(config) {
  return Object.keys(config.platforms).filter(key => Boolean(config.platforms[key])).length !== 0 
  || config.hooks && Object.keys(config.hooks).length !== 0 
  || config.assets && config.assets.length !== 0 
  || config.params && config.params.length !== 0;
}

And it builds/cleans correctly

[N1ghtly]

@stevelacy works. I previously edited my dependency config to include all the parameters they're trying to access, which works as well.

[thymikee]

Mind sending a PR with that?

[thecodrr]

@thymikee this can be closed, I think.
