What are the problems related to Promises in Firebase Cloud Functions?

edit

Some of the common problems related to Promises in Firebase Cloud Functions are:

1. The Promise chain may become too long and confusing if not handled properly.

2. It can be difficult to debug Promise errors because they are asynchronous and may not always occur in the expected sequence.

3. If a Promise is rejected, it can cause the entire chain to fail, making it difficult to identify the root problem.

4. Promises often require complex error handling to ensure that all errors are handled properly and the function does not crash.

5. If not managed properly, Promises can lead to memory leaks and other performance issues.

6. Firebase Cloud Functions has a strict timeout limit of 540 seconds, so long-running Promises can cause the function to time out and fail.
