jobs demo mosquito unable to execute job

[avrono]

running the jobs_mosquitto_demo application. The application fails with missing url despite following for example the instructions here

https://docs.aws.amazon.com/iot/latest/developerguide/iot-dc-runjobs-prepare-define.html

Believe I have the correct Policy as described here https://docs.aws.amazon.com/iot/latest/developerguide/basic-jobs-example.html

Please advise ....

Hi @avrono, Thank you for reaching out. I will look into this. Could you post logs of your error and let me know what version of the repository you are using? Best, Jason Carroll

Hi Jason,

I am using 202108.00

Also note that I tried the job client in the aws-iot-device-client repo (C++ SDK) and that works as expected.

@jasonpcarroll any word on this ?

@avrono : My apologies for the delayed reply to your inquiry.

The best reference material for the jobs_mosquitto demo is the IoT C-SDK documentation page detailing it.

While AWS IoT Jobs in general are not required to have a url parameter, this particular demo expects the url parameter to always be present so that the demo can download the file referenced by the url.

In short, to create a job that can be processed by this demo, run the following awscli command:

aws iot create-job --job-id t12 --targets arn:aws:iot:us-east-1:1234567890:thing/device1 \
  --document '{"url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.8.5.tar.xz"}'

You can change this behavior by modifying the jobs_demo_mosquitto.c file according to your own needs.
