Error from messaging.go but I am not trying to publish

[herrdragon]

Hi Team,

I am getting this error: source=messaging.go:231 msg="MessageBus trigger: Could not publish to topic '' for pipeline 'Enrich': Missing configuration 'PublishHostInfo' : Unable to create a connection for publishing"
I am subscribed to a topic but I am not trying to publish anything but it seems somewhere in the code is trying to do so but not sure why . Any ideas? Thank you

Please provide the version of EdgeX you are using.

BTW, if you set ResponseData it will attempt to publish. In your case you don't have the PublishHostInfo in your configuration. If you don't want to publish, don't set the ResponseData.

Hi Lenny,

I am running version 2.1 and I am not setting ResponseData. I have removed the PublishHostInfo to see if that would prevent from trying to publish but I still get the error.

What application service are you running? Custom or app-service-configurable?

Not the error is because PublishHostInfo is not set when it goes to publish.

Not from the code the only way it sets to line 231 is if the ResponseData is set.

Perfect! Since is checking for ResponseData != nil, I set ResponseData to nil and now I don't have the error. Thank you for your help!
