Validation.metafield Not Working – Need Assistance

[hashcott]

Hi everyone,

I successfully created a validation using the following mutation and query. Everything seemed to work correctly during setup.

However, when I try to query this validation inside a Shopify Function, the result is null.

Has anyone else encountered this issue before?
Any ideas on what might be going wrong or how to troubleshoot this?

Thanks in advance!

  target = "purchase.validation.run"

  export = "run"

run.graphql

query RunInput {
  validation {
    metafield(namespace: "$app:my-appp", key: "test-01") {
      type
      jsonValue
    }
  }
}
