react native - Firebase Crashlytics non-fatal issue in main.jsbundle

Question

I have recently been receiving emails from Firebase Crashlytics reporting that issue detected in main.jsbundle. Screenshot as per below

However if I were to click into my app's Crashlytics, I can't find this issue in the issue lists at all. Even if I filtered out the specific build version, I still can't find it.

I'm only navigated to the stack trace below, while I click on the LEARN MORE button in crashlytics's email.

It's very different from rest issue reported by Crashlytics. Any idea what is this about?

Answer 1

Are you using async/await or promise's chaining? One of your promises is not catching exceptions.

Example for async/await:

try {
  const result = await doSomething();
  ....
} catch (error) {
  console.warn(error);
}

or chaining:

doSomething
  .then(e => {...})
  .finally(...)
  .catch(error => {...})
