Is is possible to use introspection in the API?
In hasura documentation (and SO) I see it should possible but for whatever introspection query I try to use, I am getting an error (details inside)

An example from <https://hasura.io/learn/graphql/intro-graphql/introspection/|hasura introspection docs>:

```{
  __schema {
    queryType {
      fields {
        name
        description
      }
    }
  }
}```
Returns

```{
  "errors": [
    {
      "message": "Unknown argument \"limit\" on field \"__schema\" of type \"Query\".",
      "locations": [
        {
          "line": 2,
          "column": 12
        }
      ],
      "extensions": {
        "code": "GRAPHQL_VALIDATION_FAILED"
      }
    }
  ]
}```
I am getting this for every introspection query I am trying to run

Maybe introspection is disabled?
I am trying to explore the API - e.g. get object names, fields, etc...
Maybe there's another way to do it (documented somewhere?)

This only partially answers your question but there is a GraphQL playground UI made available by the Apollo container (if running on docker), I believe the default port is 4200. This UI includes access to a searchable doc with schemas and mutations.

I am using the graphql playground to run the query and getting that error.
I haven't noticed the searchable docs - *thanks for that!* 
Still - I am wondering why the introspection query fails...

Yeah those tabs for the docs and schemas are a bit hard to notice.
Unfortunately can't help you with the introspection query, haven't tried those myself.

I need to ask the team to be sure about this

So we don’t block it but you can’t do it with _the interactive api_; the interactive api automatically adds limits and offsets to queries except those we’ve explicitly exempted and the various introspection queries aren’t ones we’ve added

OK. That explains it :slightly_smiling_face:
