allowList property omitted during application of metadata snapshot

[rhyslbw]

I've prepared a minimum reproduction
Docker image hasura/graphql-engine:v1.2.1.cli-migrations

The allowList property from the provided snapshot is not applied on startup, as demonstrated by a subsequent export of the metadata with no changes:

Starting with

{
  ...
  "query_collections": [
    {
      "name": "allowed-queries",
      "definition": {
        "queries": [
          {
            "name": "allowed",
            "query": "query allowed {\n  foo {\n    id\n  }\n}"
          }
        ]
      }
    }
  ],
  "allowlist": [
    {
      "collection": "allowed-queries"
    }
  ]
}

After container starts

{
  ...
  "query_collections": [
    {
      "name": "allowed-queries",
      "definition": {
        "queries": [
          {
            "name": "allowed",
            "query": "query allowed {\n  foo {\n    id\n  }\n}"
          }
        ]
      }
    }
  ]
}

Remove, then manually re-add via console

{
  ...
  "query_collections": [
    {
      "name": "allowed-queries",
      "definition": {
        "queries": [
          {
            "name": "allowed",
            "query": "query allowed {\n  foo {\n    id\n  }\n}"
          }
        ]
      }
    }
  ],
  "allowlist": [
    {
      "collection": "allowed-queries"
    }
  ]
}
