Tasks stuck and pool blocked

Hello, I'm having this weird behaviour where tasks are queued but the function itself is not running, and runningTasks just end up pilling up...
Keep in mind that I have not changed anything in my code..

```js
console.log('1')
this[pool].queue(async worker => {
console.log('2')
let m = worker[method]
console.log(m)
if (!m) return "Method doesn't exist";
console.log('3')
q = await m(item)
console.log('4')
return q;
})
console.log('5')
await this[pool].completed()
console.log('6')
return q;
```

and from the worker file:

```
const workerFunctions= {
async gen(c) {
console.log('FUNCTION RUNNING')
..................
}
...........
}
expose(workerFunctions)
```

Behaviour:
**1
2
[Function]
3
5**

The thing is, the exposed function is not being executed at all (**FUNCTION RUNNING** is never logged) and the pool just ends up having more and more runningTasks pilling up....
