function client.DeleteObject() failed, err:

Error message

function client.DeleteObject() failed, err:

What it means

CloudflareR2.DeleteFile issues a DeleteObject call against the R2 (S3-compatible) endpoint; any SDK error from that call is wrapped in this message. The deletion API itself rejected the request — network, auth, or permission problem. Note DeleteObject is idempotent in S3 semantics; this error means the request failed, not that the key was missing.

Solutions

1. Verify CloudflareR2 config: Bucket, endpoint (https://<account>.r2.cloudflarestorage.com), AccessKey, SecretAccessKey
2. Confirm the R2 API token has Object Read & Write permission for the bucket
3. Check the wrapped err text: SignatureDoesNotMatch -> wrong secret; AccessDenied -> token lacks delete permission; DNS/timeout -> network issue
4. After fixing config, restart the server so the credentials are reloaded
5. Test with aws CLI --endpoint-url against the same bucket to isolate app vs. account issues

Example fix

// before
Endpoint: "https://r2.cloudflarestorage.com" // missing account id
// after
Endpoint: "https://<your-account-id>.r2.cloudflarestorage.com"

if cfg.Bucket == "" || !strings.Contains(cfg.Endpoint, "r2.cloudflarestorage.com") {
    return errors.New("R2 endpoint/bucket misconfigured")
}

null

err := uploader.DeleteFile(ctx, filename)
if err != nil {
    var re *smithy.OperationError
    if errors.As(err, &re) {
        // network-level: safe to retry, DeleteObject is idempotent
        return retry(3, func() error { return uploader.DeleteFile(ctx, filename) })
    }
    return err
}

When it happens

Trigger: DeleteFile(ctx, filename) when: credentials invalid, endpoint/bucket wrong, network to the R2 endpoint fails, or the token lacks permission to delete objects in the bucket.

Common situations: Rotated R2 API token still cached in config, wrong bucket name in CloudflareR2.Bucket, custom endpoint missing the account ID, firewall/DNS preventing access to <account>.r2.cloudflarestorage.com, R2 service incident.
