Cannot read property callback of undefined

Hi,
Not sure if this is a bug or something else but i am getting the following error every now and then:

I am listening to the a bsc wss endpoint and this seems to happen almost always when there are a lot of transactions (during peak hours) is there a way to capture this error, right now it is crashing my app.
My initial idea was to add a try catch but i am not exactly sure where (around the creating of the provider or around the listener) and since i cant recreate the error on demand this is hard to test

any help is much appreciated!

When the node responds to you twice for the same request, at this line, the request is actually deleted during the processing of the first response.

I think this could potentially be a bug. cc: @ricmoo

Ah makes sense! is there anything i can do to capture the error in my app until there is a fix?

This discussion is regarding v5. Are you using the latest version i.e. v6? Can you post your error and any more details here or in a new discussion/issue? Just noticed you have already created #4120
