Unable to resolve module ./src/aws-exports in demo app

[vomc]

I am reporting a bug in the aws react-native starter demo app: https://github.com/aws-samples/aws-mobile-react-native-starter

Following all steps here verbatim in terms of install and config and then doing npm run ios.

App builds and then I get the ios simulator with an iPhone 6 open and a confirmation that the build succeeded.

However then when the app starts I get that typical red reactNative error screen saying that the app was could not resolve /Users/myCompName/Documents/awsTestApp/awsChat/src/aws-exports as a folder: it did not contain a package, nor an index file

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than AWS Amplify.

What is the expected behavior?

Not sure but I assumed the demo app would just work???

Which versions of Amplify, and which browser / OS are affected by this issue? Did this work in previous versions?

You can turn on the debug mode to provide more info for us by setting window.LOG_LEVEL = 'DEBUG'; in your app.

Hey @vomc , I just tried to follow steps and had no problem running the starter. This is what I did:

npm install -g awsmobile-cli@latest
awsmobile start rn-starter react-native
cd rn-starter
npm install
npm run ios

Could you check if you have src/aws-exports.js file in project folder?

One possible cause is maybe if you are having older version of awsmobile-cli. Could you try npm install -g awsmobile-cli@latest and see if it works?

[vomc]

Ok, let me try with awsmobile-cli@latest... Though I did just install it for the first time yesterday.

[richardzcode]

is there a src/aws-exports.js file? it contains AWS configurations

[vomc]

Yup that was it. I can confirm that there is now a src/aws-exports.js and the app launches from the simulator. Thanks for the help!

Sorry to revive this, but I'm having the same issue.
Already tried to make a fresh install with npm install -g awsmobile-cli@latest and create again the project, but aws-exports.js still is missing.
Just to understand better, when is this file created?
Because here is missing too: https://github.com/aws-samples/aws-mobile-react-native-starter/tree/master/client/src

Thanks in advance.

[vomc]

Hmm interesting. Maybe try to do an npm update ? It should create an aws-exports.js file in your src folder AFAIK

Same problem don't see the aws-export.js tried npm install -g awsmobile-cli@latest and npm update.
I am running the app on windows.
Thanks

@matias91 aws-exports.js is created after you run awsmobile init, and gets updated after running awsmobile push or awsmobile pull. The file is stored on the location you specify as src folder during init.

My problem was I just ran the "awsmobile start my-project react-native" command and did not download the git code in the folder. That resolved the error but now facing a new issue:

Bundling index.android.js [development, non-minified, hmr disabled]

I have the same problem for a week, I have tried to do everything in this thread and uninstall and reinstall everything. The aws-exports.js file does not appear anywhere, any ideas?

[scrapex]

Same here. aws-exports.js does not appear.
Using
"aws-amplify": "^1.0.6",
"aws-amplify-react-native": "^1.0.6",

@Asautali @scrapex It looks like there was a change which went in about a month ago. aws-exports.js only gets generated after syncing to cloud. If you run 'amplify publish' it should pop into existence. :)

aws-amplify/amplify-cli#23 << See here for details

[scrapex]

Thanks Erica. Also seems like awsmobile cli has moved/renamed to amplify cli...

[tetreault]

Thanks @ericathegreat thats helpful. Amazon is so great at making these services but does such a poor job writing their docs haha. One would think this is mentioned, because in the react native docs for amplify it jumps right into code referencing aws-exports.
