post() and postBy() queries return null in non-default language after WPGraphQL v1.14.0

Hello,

After upgrading to WPGraphQL v1.14.0, all single post queries in the non-default language (English) now return null.

Example:

{
  post(
    id: "les-bases-de-la-guitare-la-guitare-basse"
    idType: SLUG
  ) {
    id
  }
}

Returns:

{"data": {
    "post": null
  },}

posts() queries using { where: { wpmlLanguage: $LANG } } still behaves as expected - returning posts in only the specified language:

{
  posts(first: 10, where: {wpmlLanguage: "fr"}) {
    edges {
      node {
        id
      }
    }
  }
}

Returns:

{
  "data": {
    "posts": {
      "edges": [
        {
          "node": {
            "id": "cG9zdDoxMTg0Nzk="
          }
        },
        {
          "node": {
            "id": "cG9zdDoxMTg1NDE="
          }
        },...

Any idea what might be happening here?

Best,

Matt

As a "quick fix" workaround, you could replace your single post queries with the posts query, limiting the output to one, like I mentioned in #13 (comment). It also works if you omit wpmlLanguage, but it might return the wrong language if you have posts with the same slug in different languages.

posts(where: {name: $slug, wpmlLanguage: $languageCode}, first: 1) {
  nodes {
    id
  }
}
