Optional chaining for provider with function call results in an SyntaxError

[Ventrae]

Optional chaining for provider with function call results in an error:

SyntaxError: Invalid left-hand side in assignment

example:

@rpc.controller(AppNotificationRPC).strictSerialization(false).logValidationErrors(true)
class MyController {
    constructor (private myService: MyService) { } 

    @rpc.action()
    doSomething(){
        this.myService?.itsFunction().catch();
    }
}

perhaps solution is converting it first to a temp variable, like:

(p1 = this.myService?.itsFunction, p1.Ω = [...], p1)(...)
