Gatsby sourceNode does not work with GraphQL arguments

Currently I am trying to pull some data from a API and add to GraphQL using sourceNode and createNode APIs like that:

exports.sourceNodes = async ({ actions, createNodeId, createContentDigest }) => {
const modules = ['data', 'stuff', 'bananas'];
const modulesResponse = Promise.all(modules.map(async (module) => getModuleData(module)));
const modulesData = await modulesResponse;

const content = Object.fromEntries(modules.map((entries, index) => [entries, modulesData[index]]));

actions.createNode({
    id: createNodeId(modules.join(',')),
    parent: null,
    children: [],
    content,
    internal: {
        type: 'myData',
        mediaType: 'text/html',
        contentDigest: createContentDigest(content)
    }
});

When I try to filter this (using GraphiQL) with arguments it does not appear to work:

{
  myData(content: {data: {elemMatch: {filterEntry: {eq: "foo"}}}}) {
    content {
      data {
        filterEntry
      }
    }
  }
}

It results in this:

{
  "data": {
    "myData": {
      "content": {
        "data": [
          {
            "filterEntry": "foo"
          },
          {
            "filterEntry": "bar"
          },
          {
            "filterEntry": "baz"
          }
        ]
      }
    }
  }
}
