Review Comment:
do we need to clear the metadata error right after this line? if we make it
here , it means that the `metadataError` recovered (ex. unknown/unauth topic
not in the subscription anymore), so we shouldn't be keeping/propagating any
previous error I would say. Makes sense?

Review Comment:
```suggestion

```
