Error: Comparison of: String < Integer, is not possible #684
Description
We are getting ready to upgrade from puppet 3.8 to 4.2 so we have set stringify_facts = false. Once we did that an error popped up from this module. The full error:
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: Comparison of: String < Integer, is not possible. Caused by 'A String is not comparable to a non String'. at /modules/nginx/manifests/resource/location.pp:238:17
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run
and the section in question:
$priority = 500
...
validate_array($rewrite_rules)
if ($priority < 401) or ($priority > 899) {
fail('$priority must be in the range 401-899.')
}
To force puppet to see the $priority as an integer by adding zero to it:
(https://docs.puppetlabs.com/puppet/latest/reference/lang_data_number.html#converting-strings-to-numbers)
validate_array($rewrite_rules)
if (($priority + 0) < 401) or (($priority + 0) > 899) {
fail('$priority must be in the range 401-899.')
}
