Filter creating error as an unknown argument on field


Hi, not sure if I need to get into specifics of my code just yet, but wondering if there is a reason why I cannot use ‘filter’ as an argument - in graphiql the error, as in the title of the post, is: "Unknown argument “filter” on field “calls” of type “Query”."
Am I entirely missing something from the docs, including - I read it that I can use ‘filter’ as an argument in any query? But do I need to set something up? For some context, the app is using Node, React, and React Apollo.

Thanks in advance for any tips that can push me in the right direction!


Can you share the query you are trying to execute, and preferably your schema?


Same here:

I don’t know what I’m missing.
