Query products by a metafield value

[j-riv]

I'm trying to query all products in a collection by a metafield value. This seems to be possible with the storefront api according to this page.

https://shopify.dev/api/examples/filter-products#query-products-by-metafield-value

I created a product metafield of true / false type. The following query returns all products, no matter what I put as the value. What am I doing wrong?

query exampleFilteredQuery {
  collection(handle: "filterable-collection") {
    handle
    products(first: 25,
     filters: {
        productMetafield:{
          namespace:"my_namespace",
          key:"my_metafield_key",
          value:"true"
        }
      }) {
      edges {
        node {
          id
          title
        }
      }
    }
  }
}

Apparently I had missed something, so posting it here just in case it helps someone else. Make sure you have done all the following:

1. The products are published to the online store channel.

2. The metafield filter has been added as an available filter under Online store->Navigation->Collection and Search Filters.

3. The metafield types are any of numeric_decimal,numeric_integer,boolean,single_line_text_field.

4. You're using API version 2022-04 or higher.
