[Bug]-[5000]:async tag not assigned in absence of null checks

Is there an existing issue for this?

[X] I have searched the existing issues

Description

Missing null checks in Js objects result in async tag not getting assigned to a function.

This is because, we do a dry run of the method and it throws Cannot read properties of undefined. Before the execution reaches the async part of the code.

Steps To Reproduce

export default {
    myVar: [],
    myVar2: {},
    myFun1: () => {  
        //this.myVar[0].id;
        //this.myVar2.data.id;
        return Api1.run()
    },
}

Uncomment the lines in myFun1 and notice the async tag is not assigned anymore. (Even if Api1.run() is async)
When null checks are added the tag will be assigned properly.
```
this.myVar[0]?.id;
this.myVar2.data?.id;
```
