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

Sylvain Hazard · Answer

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

Kevin Kho · Answer

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
