Groovy, AWS CLI, Active Choices Reactive Parameter and Jenkins

// Get list of IPS from AWS CLI and populate Active Choices Reactive Parameter

def command = 'aws ec2 describe-instances --filters Name=tag:Name,Values=Test --query Reservations[*].Instances[*].PrivateIpAddress --output text'
def proc = command.execute()
proc.waitFor()              

def output = proc.in.text
def exitcode= proc.exitValue()
def error = proc.err.text

if (error) {
	println "Std Err: ${error}"
	println "Process exit code: ${exitcode}"
	return exitcode
}

//println output.split()
return output.tokenize()

I'm having an issue when I introduce the tag key, like so

def command = 'aws ec2 describe-instances --filters Name=tag:environment,Values=CF-LAB --query 'Reservations[*].Instances[*].{ID:InstanceId,NAME:[Tags[?Key==`Name`].Value[] | [0]]}' --output text'

def proc = command.execute()
proc.waitFor()              

def output = proc.in.text
def exitcode= proc.exitValue()
def error = proc.err.text

if (error) {
	println "Std Err: ${error}"
	println "Process exit code: ${exitcode}"
	return exitcode
}

//println output.split()
return output.tokenize()

It looks like a syntax issue, but I cannot figure out why. any idea?
Thanks

try this -
def command = 'aws ec2 describe-instances --filters Name=tag:environment,Values=CF-LAB --query \'Reservations[*].Instances[*].{ID:InstanceId,NAME:[Tags[?Key==Name].Value[] | [0]]}\' --output text'
