## PR-Codex overview
This PR focuses on improving the handling of messages received in web
workers by adding a check to ensure the data received is an array before
destructuring it. This change enhances the robustness of the code by
preventing potential errors when processing unexpected message formats.

### Detailed summary
- Added a check to verify if `e?.data` is an array before destructuring
it into `[eId, data]`.
- Maintained the existing logic for resolving or rejecting the promise
based on the `data.success` property.
