Hello there!!
I am trying to create a custom header using transform rulesets.
I am seeing “Error: error creating ruleset Adding trace id request header: missing the permissions required to create zone rulesets in the http_request_late_transform phase”
Code snippet as follows:
kind = “zone”
phase = “http_request_late_transform”
rules {
action = “rewrite”
action_parameters {
headers {
name = “x-b3-traceid”
operation = “set”
expression = “to_string(cf.ray_id)”
}

I am referring to examples from here https://developers.cloudflare.com/rules/transform/request-header-modification/create-api/ for ^ code
