   <!-- Bito Reply -->
   The flagged issue is correct. The `canOverwriteSlice()` method currently 
evaluates to `true` for admins even when `this.props.slice` is `null` (a new 
chart), which leads to a runtime error when `saveOrOverwrite()` attempts to 
destructure `slice_id` from an undefined object. To resolve this, you should 
add a check to ensure `this.props.slice` exists before allowing an overwrite.
   
   Here is the corrected implementation for `canOverwriteSlice` in 
`superset-frontend/src/explore/components/SaveModal.tsx`:
   
   ```typescript
     canOverwriteSlice(): boolean {
       const canEdit =
         this.props.can_overwrite ||
         isUserAdmin(this.props.user) ||
         this.isCurrentUserOwner();
       return !!this.props.slice && canEdit && 
!this.props.slice?.is_managed_externally;
     }
   ```
   
   There are no other review comments in this pull request to address.
   
   **superset-frontend/src/explore/components/SaveModal.tsx**
   ```
   canOverwriteSlice(): boolean {
       const canEdit =
         this.props.can_overwrite ||
         isUserAdmin(this.props.user) ||
         this.isCurrentUserOwner();
       return !!this.props.slice && canEdit && 
!this.props.slice?.is_managed_externally;
     }
   ```
