A snippet of the error is given below:
{message: 'A listener indicated an asynchronous response by r…age channel closed before a response was received'}
message: "A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received"I would like to share the steps that helped me to fix the error; “A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received”.
Why “A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received” error is seen?

Some extension appear in your local host and need to be trusted to immediately fix this error.
A simple solution to fix this would be to run your file in incognito mode and you will see that your error is fixed.
