Kafka Admin CreateTopic crashes Node Red... #40

Closed mitch-shiver closed 2 years ago

mitch-shiver commented 2 years ago

Hi Peter,

Pretty cool idea to wrap kafka admin functions in a node red node. I seem to be having an issue using it though, maybe it is something in my configuration. I have a Linux system that is running Node Red, specs below under My configuration. When I create the Node Red workflow in the image below under My flow using the Kafka Admin node, I get the exception under My exception, and Node Red crashes.

(visually worked out from the test image at https://github.com/peterprib/node-red-contrib-kafka-manager#tests; I could not get the generalTest.json file to work, see details below. The json file for my attempt is attached)

My configuration:

My flow: image

My exception:

9 Dec 10:57:38 - [red] Uncaught Exception:
9 Dec 10:57:38 - TypeError: topics.every is not a function
    at KafkaClient.createTopics (/home/pmc/.node-red/node_modules/kafka-node/lib/kafkaClient.js:931:14)

Another question - How do you create that nice admin page under https://github.com/peterprib/node-red-contrib-kafka-manager#simple-web-admin-panel, is that part of package and I just did not find it yet?

Thanks! Mitch

Can I assume you worked out your problem as will fix the problem. The admin panel is based on standard node-red features. See problem is in module it calls. If you can give details I will see if I can put check in so ensure null topics are not is sent to client. Is it correct to assume message sent did not have a list of topics?

Hi Peter, Yes, it was mostly ignorance on my part, so I closed the issue... Thanks!Mitch On Friday, December 10, 2021, 06:48:43 PM PST, Peter Prib @.***> wrote:
