amplify-js: Error: evaluating 'global.TYPED_ARRAY_SUPPORT'

Ok, after some testing today I can confirm that Error: evaluating 'global.TYPED_ARRAY_SUPPORT' is 100% caused by babel --presets env in combination with amazon-cognito-identity.js.

I did change this:

{
  "presets": ["env",  "react-native"]
}

To this:

{
  "presets": ["react-native"]
}

Thanks to @AceNorth for confirming this.

Remember to completley rebuild your app and remove all temporary files to be clean:

1. remove all from C:\Users\Megajin\AppData\Local\Temp.
2. remove the folder node_modules .
3. install all packages with npm install --no-optional.
4. In current windows console: set RNFB_ANDROID_PERMISSIONS=true (this is for the current session so I can link react-native-fetch-blob).
5. react-native link

I guess the Issue can be closed as resolved @powerful23 @elorzafe

You guys might find this useful too: @paul-doherty @AndrewSouthpaw @michalziolkowski

Ok I found what my problem was. I was excluding node_modules in my tsconfig like below.

"exclude": [
    "node_modules"
  ],

Turns out this doesn’t exclude it. I set my rootDir to force it to exclude node_modules and now all is good

"rootDirs": [ "app" ],

Thanks

@powerful23 @paul-doherty

It is working now for me. I did the following:

1. remove all files from my C:\Users\Megajin\AppData\Local\Temp.
2. removed the folder node_modules .
3. installed all Packaages with npm install --no-optional.
4. In current windows console: set RNFB_ANDROID_PERMISSIONS=true (this is for the current session so I can link react-native-fetch-blob).
5. react-native link

Everything works as expected, but I still do not know what the cause was. I recommend everyone having the same issue to follow my steps above and try a clean install of all packages. If the error still occurs try to remove packages one by one and start with your devDependencies.

I should mention that I did a gradle upgrade. I’ll provide my new updated sources for the android folder:
