Firebase (sdk) The requested document was not found.
Understanding Firebase Firestore
Firebase Firestore is a flexible, scalable database for mobile, web, and server development. It is part of the Firebase suite of tools, which provides backend services for building applications. Firestore is a NoSQL document database that allows developers to store, sync, and query data for their applications on a global scale.
Identifying the Symptom: Firestore Document Not Found
When working with Firestore, you might encounter the error code firestore/not-found. This error typically occurs when a requested document cannot be found in the database. The symptom of this issue is an error message indicating that the document you are trying to access does not exist.
Explaining the Issue: Firestore/not-found Error
The firestore/not-found error is thrown when the Firestore client attempts to retrieve a document that does not exist at the specified path. This can happen if the document path is incorrect or if the document has been deleted or never created.
Common Causes of the Error
- Incorrect document path: The path specified in the query does not match any document in the database.
- Document does not exist: The document may have been deleted or never created.
Steps to Fix the Firestore/not-found Issue
To resolve the firestore/not-found error, follow these steps:
Step 1: Verify the Document Path
Ensure that the path you are using to access the document is correct. Double-check the collection and document IDs in your query. For example, if you are using the following code:
const docRef = firestore.collection('users').doc('user123');
Make sure that both 'users' and 'user123' are correct and exist in your Firestore database.
Step 2: Check Document Existence
Use the Firestore console or a query to verify that the document exists. You can use the following query to check if a document exists:
docRef.get().then((doc) => {
if (doc.exists) {
console.log('Document data:', doc.data());
} else {
console.log('No such document!');
}
}).catch((error) => {
console.log('Error getting document:', error);
});
Step 3: Create the Document if Necessary
If the document does not exist, you may need to create it. Use the set() method to add a new document:
docRef.set({
name: 'John Doe',
email: '[email protected]'
}).then(() => {
console.log('Document successfully written!');
}).catch((error) => {
console.error('Error writing document: ', error);
});
