importing functions from '@react-native-firebase/functions' always fails

[tycali17]

Whenever I run any project with that import, it fails with 'native module cannot be null'. React Native clearly auto linked them, I've tried re-installing, manually linking to iOS, and so much more. I cannot for the life of me get my app running without errors and thus cannot use firebase functions in react native. How can I ensure the import stops breaking the app? I even see the node module folder 'functions' with content inside. I used yarn add for RNFBApp & RNFBFunctions

I hope someone can assist, I've spent literally several months on this issue and read maybe 100 posts so far.

Have you tried examining a working app? This will create one, then you can see it run (which serves two purposes: proves it can work which is sometimes needed to maintain the courage to continue on, and gives you something to compare with your app so hopefully you can find the problem) https://github.com/mikehardy/rnfbdemo/blob/master/make-demo.sh

thanks, I've read the docs so many times but will keep practicing. I'm at least on the right track finally. Thanks again

In case it helps, I have a generic "sendSuccess" function that I call in all my functions to handle some log correlation header stuff but also to wrap the result so that it is in the correct format, it looks like this in typescript and I call it with the "res" object you are passed to start the function, and any arbitrary object that can be JSON stringified:

export function sendSuccess(
  res: functions.Response,
  // eslint-disable-next-line @typescript-eslint/no-explicit-any
  body: { result: any }
): functions.Response {
  console.log(
    Date.now() +
      ' Success Correlation-ID: "' +
      res.locals.correlationId +
      '" kullkiId: "' +
      res.locals.kullkiId +
      '" body: "' +
      JSON.stringify(body) +
      '"'
  );
  const response = res
    .set('X-Correlation-ID', res.locals.correlationId)
    .send(JSON.stringify({ data: body }) + '\n');
  return response;
}

I use command-line curl to test these things while developing, and then when I first hook them up in an app I usually console.log(JSON.stringify(theResponseObjectIGot)) in order to make sure my object shape is what I expected, and I very slowly inch forward until I have a new feature done

Hope this helps

It does, very much. Will certainly give this a go along with curl testing. Many thanks

So I've had success up to the point where I have to call the function that I put on firebase. It's now saying I need to link the functions() module or add to podfile after I used yarn add + pod install etc.

Do you suggest basically continuing to comb through the demo and compare files with my project to ensure it works properly? Also noticed @FirebaseSdkVersion is set in demo but it runs me into version conflicts for the related firebase dependencies. Not sure if I need the $FirebaseSDKVersion set or not.

If I should just keep comparing projects I will do so, thanks in advance for any help.

If the demo works and your project doesn't, either continue combing through the demo or do a large scale harvest-logic-from-project / drop-it-in-working-demo replace of the broken project
