Error when running in debug mode

[vuphuctho]

Project dependencies

• react-native 0.51.0
• react-native-obfuscating-transformer ^1.0.0-rc.0

Problem details

• Add two files with info shown in Usage
• run react-native run-ios to start app in debug mode

Observation Following error was thrown in console:

Bundling `index.js`  [development, non-minified]  0.0% (0/952), failed.
error: bundling failed: Error: original.line and original.column are not numbers -- you probably meant to omit the original mapping entirely and only map the generated position. If so, pass null for the original mapping instead of an object with empty or null values.

My temporary fix is to put a check in rn-cli.config.js. This works, but I expect an official fix for this.

if (process.env.NODE_ENV === 'production') {
  module.exports = {
    getTransformModulePath() {
      return require.resolve("./transformer")
    },
  }
}

Hi :heart: :wave:

Which version of source-map do you have? run this command and paste the output here:

cat node_modules/source-map/package.json | grep version

  "version": "0.5.7"
