Why am I getting a "Doc not found" error in Firebase?

"Why am I encountering a 'Doc not found' error in Firebase?"

Encountering a "Doc not found" error in Firebase typically means that your application is trying to access a document that doesn't exist in the Firestore database. Here are some common reasons and how to address them:

Incorrect Document ID: Ensure that the document ID you're trying to access is correct. Double-check for typos or case sensitivity issues.

Document Deletion: Verify that the document hasn't been deleted. If it was deleted, attempting to access it will result in a "Doc not found" error.

Query Issues: If you're using a query to retrieve documents, ensure that the query is correctly formed and that it matches the documents in the collection.

Permissions: Check that your application has the necessary permissions to access the document. Firestore security rules might be preventing access.

Firestore Setup: Ensure that Firestore is properly set up in your Firebase project and that the database URL is correctly configured in your application.
