GraphQL SKU Lookup problem, appears to be searching other fields as well.

[djhamilton]

I have been using GraphQL for some time on other stores and everything has been working perfectly.
Introduced this to a new store today, and i am getting very random results.

From what i can see the Query for GraphQL i am running appears to be searching in more than just the SKU field. When searching for words or other strings in the SKU Variable
i can see results that are matched in the body_html (As if the Query is also searching in there)

Is this common? or do i have a typo / mistake in my Query.

Query:

query ($first: Int, $sku: String)
{ productVariants(first: $first, query: $sku) {
    edges {
      node {
        title
        id
        sku
        product {
          title
        }
        inventoryItem {
          id
          inventoryLevels(first: 3) {
            edges {
              node {
                id
                available
                location {
                  id
                  name
                  address {
                    city
                  }
                }
              }
            }
          }
        }
      }
    }
  }
}

And my Variables.

{
  "first": 5,  
  "sku":"555"
}

In this case the SKU is searching for 555, the product it returns has a SKU of 12574, When i do a product lookup using the Rest API, i can see that 555 appears in the Body_html.

So when i replace 555 with a string found in the body_html it also returns that line, Making me thing i have an error / formatting issue in my GraphQL Query / Structure

Would appreciate any guidance on this

I know what the issue is:

query ($first: Int, $sku: String)
{ productVariants(first: $first, query: $sku) {
    edges {
      node {

This needs to be something like:

query ($first: Int)
{ productVariants(first: $first, query: "sku:555") {
    edges {
      node {

As it needed to be a variable, i was unsure how to format it, I fudged the variable but and now appears to be working.
I am interested in the correct formatting for       query: sku: $sku     Though

Here is the fudge:

{
  "first": 5,  
  "sku": "sku:555"
}

Basically passing the search field sku: in the variable
