Identifying the Symptom: Bucket Deletion Failed

When working with Supabase Storage, you might encounter an error message indicating that a bucket deletion has failed. This symptom is typically observed when attempting to remove a storage bucket from your Supabase project and receiving an error response.

Common Error Message

The error message might look something like this: "BucketDeletionFailed: An error occurred while attempting to delete a storage bucket."

Exploring the Issue: Why Bucket Deletion Fails

The "BucketDeletionFailed" error usually arises when the bucket you are trying to delete is not empty or is currently in use. Supabase Storage requires that a bucket be completely empty before it can be deleted to prevent accidental data loss.

Root Causes

The bucket contains files or objects that have not been removed. The bucket is being accessed or used by another process or application.

Steps to Resolve the Bucket Deletion Issue

To successfully delete a bucket in Supabase Storage, follow these steps:

Step 1: Verify Bucket Contents

Ensure that the bucket is empty. You can list the contents of the bucket using the Supabase Storage API or the Supabase Dashboard. Refer to the Supabase Storage API documentation for more details.

const { data, error } = await supabase .storage .from('your-bucket-name') .list('')if (error) console.log('Error listing files:', error)else console.log('Files in bucket:', data)

Step 2: Remove All Files

If the bucket is not empty, delete all files within it. You can use the following command to remove files:

const { error } = await supabase .storage .from('your-bucket-name') .remove(['file1.jpg', 'file2.png'])if (error) console.log('Error removing files:', error)

Step 3: Ensure No Active Usage

Check that no other processes or applications are using the bucket. This might involve reviewing your application code or monitoring active connections.

Finalizing the Deletion

Once the bucket is confirmed to be empty and not in use, attempt to delete the bucket again using the Supabase Dashboard or API:

const { error } = await supabase .storage .from('your-bucket-name') .removeBucket()if (error) console.log('Error deleting bucket:', error)
