## PR-Codex overview
This PR focuses on improving error handling by adding `try-catch` blocks around asynchronous calls in the `getContractCreator` function. This change ensures that if an error occurs during the execution of `owner` or `getRoleMember`, the function will return `null` instead of throwing an unhandled error.

### Detailed summary
- Wrapped the calls to `owner` and `getRoleMember` in a `try-catch` block.
- Changed the calls to `owner` and `getRoleMember` to use `await` for proper asynchronous handling.
- Ensured that if an error occurs, the function returns `null` instead of failing silently.
