@AliNaraghiA is this a valid issue still or did you fix it? I'm not sure based on your last comment.

@jasonbahl No, I still have a problem. I can't call the post with the slug:

query PostBySlugEn($slug: ID!) {
post(id: $slug, idType: SLUG) {
title
content
postId
featuredImage {
node {
sourceUrl
altText
}
}
}
}

---

QUERY VARIABLES:
{
"slug": "سلام"
}

---

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

But I have a post with {slug: سلام} in WordPress posts.
