[leda-dev] SeatAdjusterApp launch in Leda

[Antara Dey <Antara.Dey@xxxxxxxxxxxxxxxxxx>]

Hello Leda Community,

 

I am a student currently working at ITK.

I, and my team have been exploring Eclipse Leda, to understand its underlying functionality and how it interacts with the contributor pieces of SDV.

I am currently facing a challenge with debugging the application container in Leda and seek some support on it.

 

First, I used to Velocitas examples tutorial to launch the services in VS Code and traced the logs.

Then, I followed the Leda documentation and launched the Seat Adjuster Vehicle App as a Kanto-CM container in Leda. I used the Dockerfile from Velocitas repository to create a docker image – which includes the necessary modifications for it to work.  All other containers are also successfully up and running.

 

Issue: The SeatAdjusterApp does not work as expected in Leda. It does not launch completely. It subscribes to MQTT topic /seatadjuster/setPosition/request. But, as seen from the Kantui logs, it fails to further subscribe to the VehicleDataBroker. Due to this, the MQTT publish message command (move seat position) does not render any output from the app. The functionality of the application works as expected in Velocitas.

 

I have attached the Container Manifest, Dockerfile and Kantui logs for your reference.

 

Kindly provide support and/or information on this issue to proceed further.

 

Best regards,

Antara Dey
