kura - cannot uninstall deployment package remotely(deploy-v2) - osgi

Question

I am new to kura and I have been trying to remotely uninstall a deployment package using Amit's MQTT application, but I am unable to do so. This is the request payload I send from the application-
dp.name=hello_osgi
job.id=12345891011L
dp.version=1.0.0
I get the following error in the response topic-
-- listing properties --
response.code=500
response.exception.message=java.lang.String cannot be cast to java.lang.Long,
response.exception.stack=java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long

Malformed uninstall request
Following is the kura console-

Is there some other way to send the request payload ?

Answer 1

A quick look at DeploymentPackageUninstallOptions reveals that you are sending job.id as a String instead of a Long.
Instead of
String reqId = "12345891011L";
payload.addMetric("job.id", reqId);
the code should do
long reqId = 12345891011L;
payload.addMetric("job.id", reqId);
Or better, use KuraUninstallPayload which already implements all methods with the correct type.
I don't know Amit's MQTT UTility, but I think you can set the type of the variable in some way (or change his application to set the correct type and then send a pull request).
