Issues rendering ERB template for nats.private_key and nats.cert_chain properties

[jriguera]

We are trying to define those properties for NATs TLS configuration as they are not part of the links, but the ERB template does not render the values, they are always empty.

We think the problem is in

promfetcher-release/jobs/promfetcher/templates/config.yml.erb

Lines 37 to 40 in 456fdd6

	nats_cert_chain = ''
	nats_private_key = ''
	if_p("nats.cert_chain") { |val| nats_cert_chain = val }
	if_p("nats.private_key") { |val| nats_private_key = val }

The values of those 2 variables always are empty

 nats_cert_chain = '' 
 nats_private_key = '' 

The solution we have found is changing the code to:

  nats_cert_chain = ''
  nats_private_key = ''
  if_p("nats.cert_chain") do |val|
    nats_cert_chain = val
  end
  if_p("nats.private_key") do |val|
    nats_private_key = val
  end

We are using BOSH Director versions:

Version            280.0.23 (00000000)
Director Stemcell  -/1.423
