Error when consuming more messages that exist in topic

[vvargas90]

Steps to reproduce:

• Create a Reader with offset 10
• Last offset of the topic is 13
• I want to consume 10 messages

Expected result
I just get 3 messages back, as are the ones that exist in the topic

Actual result
I get the 3 messages back but I have an error I can't even catch in k6:

It comes from here https://github.com/mostafa/xk6-kafka/blob/main/reader.go#L344 but I can't capture it as an XK6KafkaError.

@vvargas90

This is the expected behavior based on the current design. Would be happy to see contributions.

Why is that? It's not even possible to see what the error is @mostafa

@davidgomesdev @vvargas90

Good question! I am trying to fix it. Will raise a PR soon and would be happy to have your feedback.

[mostafa]

@davidgomesdev @vvargas90 Can you test the changes?

[davidgomesdev]

Hi @mostafa, I was referring to it lacking details, rather than not being catch-able, it now indeed is possible to catch the error, but I wanted to see more information regarding the error itself.

[mostafa]

@davidgomesdev I won't be able to decipher the error any more than you do. I made the kafka-go's error catch-able, so you can search the error in that library.

This was what I meant @mostafa #288
