[AchrafBn]

After uploaded image to cloud storage I'm getting this error , Any clue please ?

Sample code

 const onUpload = async (
    uri
  ) => {

    try {
      const file = await FileSystem.readAsStringAsync(uri, {
        encoding: FileSystem.EncodingType.Base64,
      });
      const ref = await storage().ref().child(currentUser.uid);
      let snap = await ref.putString(file, "base64");
      const url = await snap.ref.getDownloadURL();
    } catch (e) {
      console.log("Error", e);
    }
  };

Hi there!
No idea, sorry. You should run the project from Xcode and watch the console. An internal error is typically accompanied by some messaging from firebase-ios-sdk in the lower-level logs

I am having this exact same issue. No clue as to what is causing it yet, but please keep me updated!

Any updates on this? I'm getting this error... the first time I install the app I can upload any image once... then it keeps throwing this error

Hey anyone found any solution yet? I am facing the same issue on ios simulator -

Error: [storage/unknown] An unknown error has occurred.

I didn't get this error when testing on IOS device, but it shows only on ios simulator

This the true answer unfortunately

I also have the same issue but in android?

[Pramod058]

This is because of the TEST MODE while initializing firebase database. It expires in 1 month and throw this error.

@Pramod058 could you elaborate what TEST MODE is and how can we config it to avoid the issue?

[lsps9150414]

Hey @Pramod058 it'll be really helpful if you could share more details on this 🙏🏻

I re-build my project in x-code.

it worked for me

[zahid502]

Erase the device content and settings and then build, it worked for me.
It's due to simulator

Try with a small-sized image.

Any updates on this? It happens to me quite randomly. What would be possible reasons?

[mikehardy]

I've never had good luck guessing at reasons people state happen to them randomly, but without specifying any details on reproduction. Have you?
