Way to get the parameters associated with a named query?

Ignition
8

This is where I ended up with, which I call with a system.util.sendRequest

def getNamedQueryParameters(payload):
	from com.inductiveautomation.ignition.gateway import IgnitionGateway
	project = payload['project']
	query = payload['query']
	namedQuery = IgnitionGateway.get().getNamedQueryManager().getQueryFromPath(project, query)
	parameters = namedQuery.getParameters()
	listOfParams = [param.getIdentifier() for param in parameters]
	logger.info(str(listOfParams))
	return listOfParams

And this logs exaclty what I need so I can utlize it.

I am testing it in script console now though and I actually am not getting the result - is that a known thing with testing sendRequest in script console?

project = 'PSM4_Project'
messageHandler = 'getNamedQueryParameters'
d = {'project':project, 'query':'forms/Customer/get'}
result = system.util.sendRequest(project, messageHandler, d)
print str(result)
print str(type(result))

Gives me None/NoneType, but I would expect the list of params that are logged. I assume it will work in the client, I just like to try to build these things in script console as I find it easier to debug and fix issues.

EDIT: Issue with sendRequest was of course my own mistake. I had

def handleMessage(payload):
	classes.helpers.getNamedQueryParameters(payload)

but needed

def handleMessage(payload):
	return classes.helpers.getNamedQueryParameters(payload)
