Topic is being created OK, but no messages are produced

[jseparovic]

Hi,

I can't seem to get the adapter to produce any messages to the topic.

It creates the topic ok, but it's empty.

Do you think it's related to the partition count message from above?

Under debug I see metrics in the logs no problem:

...

Any ideas?

I reduce datas,err:Failed to obtain reader, failed to marshal fields to JSON, json: unsupported value: NaN,but I don't know how to approve it,maybe metrics are not standard JSON datas or we need transfer part datas.
