fix(array-to-string-conversion): Fix array to string conversion error in webhook registration

[crisalice]

WHY are these changes introduced?

While checking a webhook record, an "Array to string conversion" error was encountered. This error occurs when the code tries to concatenate or output an array directly as a string. In this specific case, the $checkBody variable was being used directly inside a string, causing the error.

WHAT is this pull request doing?

This pull request addresses and resolves the "Array to string conversion" error that occurs during the webhook registration check in the application. The error was caused by attempting to concatenate an array directly within a string.

Thank you for contributing! I just have one minor nit: could we move line 193 inside the if block, so we're not always converting the payload back to a string?

Thank you for the feedback! I've adjusted and moved the string conversion to line 193 inside the if block.
