Directly concatenating server response body to error messages could expose sensitive information like API keys, tokens, or internal system details in logs. Consider sanitizing the response body or limiting the amount of data included to prevent information disclosure.

Suggested change

	// Enhance error message with response body details for better debugging
	clientError.message = clientError.message + ' - Server response: ' + bodyMsg;
	// Enhance error message with a sanitized/truncated response body for better debugging
	clientError.message = clientError.message + ' - Server response (truncated): ' + getSafeErrorBodySnippet(bodyMsg, contentType);

[Copilot]

[nitpick] The error message formatting could be improved by using template literals for better readability: clientError.message = ${clientError.message} - Server response: ${bodyMsg}``

Suggested change

	clientError.message = clientError.message + ' - Server response: ' + bodyMsg;
	clientError.message = `${clientError.message} - Server response: ${bodyMsg}`;
