Hi Hans-Peter,
I totally agree with Hans Van Akelyen. We have kafka consumer in
production without any problem so a reproduction path is very welcome.

Hi Hans-Peter,
A freezing UI is definitely a no-go so I am interested in a
reproduction path for this so we can avoid this.
The Kafka transforms have received some love and are being used in
projects so I'm sure we will figure it out.
As getting all the information via email might be a painful process,
feel free to reach out to me on hansva[at]apache.org
<http://apache.org> with your timezone so we can plan a short call to
go over your problem.
Cheers,
Hans

Hi,
No kafka is not in a docker container.
Even then the kafka pokemon producer and consumer would have the
same issue.
Perhaps I am on to something.
When I click on Output and choose show input fields a window pops
up "Searching for input fields..."
That hangs.
I must have missed something with the fields. It seems that just
copying the file does not work as I expected 😑

Are you using Kafka in docker? If yes be sure the networking
is configured correctly.

Hi,
Yes I have 2 topics and tried both.
One is filled with a console-producer
The other one with the sample pokemon producer.
When I modify the parameters Hop-gui comes up with auto
suggest ..
The state always remains : Initializing .
After that it spins out of control (Hop-gui does not respond
anymore).
Regards Hans-Peter

Ciao Hans,
I strongly suggest to review your configuration. It seems
to me that you
are pointing to the wrong topic because no data is coming
in. Are you
sure you are reading from the same topic you are writing to?
Cheers
