Distinct argument not listed in schema

[hi019]

What version of GraphJin are you using? graphjin version

Latest - v0.20.16

Steps to reproduce the issue (config used to run GraphJin).

Any config.
In the graphql web ui, run a query with a distinct argument. It should run successfully. Then, open the schema panel and find the arguments for the resolver you just queried. The distinct argument shouldn't be listed there, even though it's actually accepted by Graphjin
