E0714: 'async' keyword is not allowed on getters or setters
Use of 'async' keyword, defining asynchronous functions, is not allowed on getters or setters. Getters and setters are synchronous operations and do not support the asynchronous functionality.
To fix this error simply remove 'async' keyword from getters and setters, so they can function properly as synchronous operations.
However, if you require asynchronous behavior within getters or setters, you can achieve this by implementing separate asynchronous methods.
