Date / eq operator DateFilter bug in GraphQL

Describe the bug

Having an issue querying by date field in GraphQL. eq operator not working correctly in DateFilter via GraphQL. The query works if I hardcode the date into the query, but fails if I make it a variable. Bug?

Also, documentation appears to be wrong on the filters that Dates support (“in” for example, doesn’t work) https://www.sanity.io/docs/graphql#1c12c1798386

To Reproduce

In my model, date is a date field.

Query variables: {date: "2021-06-22"}

query GetThing($date:Date) {
    allThing(where:{date:{eq: $date}}) {
    _id
    date
  }
}

Expected behavior

The query above returns 0 results. It should return 1 matching document:

{
  "data": {
    "allThing": [
      {
        "_id": "c9592994-303b-4e6e-92e4-e77309e640dd",
        "date": "2021-06-22",
      }
    ]
  }
}

Hardcoding date as string returns the correct result:

query GetThing {
   allThing(where:{date:{eq: "2021-06-22"}}) {
    _id
    date
  }
}

Specifying an earlier date, then using gte returns the correct result. Query variables: {date: "2021-06-21"}. Does not solve my use case, but does highlight the issue.

query GetThing($date:Date) {
    allThing(where:{date:{gte: $date}}) {
    _id
    date
  }
}

This sounds like a bug, given your variable is in the correct format. I’ll take a look at this on Monday and check out what is going on when you pass a variable.
