Explanation:
The error message “object async_generator can’t be used in ‘await’ expression” indicates that you are trying to use the ‘await’ keyword with an object that is not an asynchronous generator.
In JavaScript, the ‘await’ keyword is used to wait for a Promise to resolve and get the result. It can only be used within an async function, which is declared with the ‘async’ keyword.
However, the object you are trying to use with ‘await’ is not an asynchronous generator, which means it does not return a Promise. As a result, you cannot use ‘await’ with that object.
Example:
async function fetchData() {
const data = await myAsyncGenerator(); // 'await' expression using an asynchronous generator
console.log(data);
}
async function myAsyncGenerator() {
// Some asynchronous logic...
}
In the above example, the function ‘fetchData’ is an async function that uses the ‘await’ keyword to wait for the result of ‘myAsyncGenerator’. ‘myAsyncGenerator’ is an asynchronous generator function that returns a Promise. Therefore, using ‘await’ with ‘myAsyncGenerator’ is valid.
Additional Information:
To fix the error, make sure you are using ‘await’ with an asynchronous generator function or a Promise. If the object you are working with is not an asynchronous generator, you might need to check its documentation or implementation to find the appropriate way to wait for its result.
