Firebase (sdk) Encountering a 'storage/object-not-found' error when trying to access a Firebase Storage object.
Understanding Firebase Storage
Firebase Storage is a powerful, scalable, and secure object storage service provided by Firebase. It allows developers to store and serve user-generated content such as images, audio, and video files. Firebase Storage is built for app developers who need to store and serve large amounts of unstructured data directly from their applications.
Identifying the 'storage/object-not-found' Symptom
When working with Firebase Storage, you might encounter the 'storage/object-not-found' error. This error typically occurs when you attempt to access a storage object that does not exist at the specified path. The error message is usually accompanied by a code that helps identify the issue.
Exploring the 'storage/object-not-found' Issue
What Causes This Error?
The 'storage/object-not-found' error is triggered when the Firebase SDK cannot find the object at the specified path in your Firebase Storage bucket. This can happen if the object was deleted, the path is incorrect, or the object was never uploaded.
Common Scenarios
- Attempting to download or access a file that has been deleted.
- Using an incorrect path or filename when referencing the object.
- Trying to access a file before it has been successfully uploaded.
Steps to Resolve the 'storage/object-not-found' Error
Verify the Object Path
Ensure that the path you are using to access the object is correct. Double-check the bucket name, directory structure, and filename. You can use the Firebase Console to navigate through your storage bucket and verify the path.
Check Object Existence
Use the Firebase Console to confirm that the object exists at the specified path. If the object is missing, you may need to re-upload it. You can also use the Firebase SDK to list objects in a directory to verify their existence:
const storageRef = firebase.storage().ref();
storageRef.child('your-directory/').listAll()
.then((res) => {
res.items.forEach((itemRef) => {
console.log(itemRef.name);
});
})
.catch((error) => {
console.error('Error listing objects:', error);
});
Re-upload the Object
If the object is missing, upload it again using the Firebase SDK or the Firebase Console. Ensure that the upload completes successfully and that the object appears in the expected location.
