the best fix I figured out is just pass an empty object to the singlePost() function then assign the destructed data to it:
function SinglePost(props,args={}) {
const postId = props.match.params.postId;
const { user } = useContext(AuthContext);
const commentInputRef = useRef(null);
const [comment, setComment] = useState('');
const{ data:{getPost} = args } = useQuery(FETCH_POST, {
variables: {
postId
}
});

Thank you so much for this solution!! working fine for me.

As answered in the other question:
const { data = {} } = useQuery(FETCH_POST_QUERY, {
variables: {
postId,
},
});
const thisPost = data.getPost;
....
let postMarkup;
if (!thisPost) {
postMarkup =Loading Post...
;
} else {
const {
id,
body,
createdAt,
username,
// comments,
likes,
likeCount,
commentCount,
} = thisPost;
Works but gets stuck on Loading...

@aindriu80
you have to return only datalike this:
const { data } = useQuery(FETCH_POST_QUERY, {
variables: {
postId,
},
});
from classsed-graphql-mern-apollo.
...
const { loading, data } = useQuery(FETCH_POST, {
variables: {
postId,
},
})
let getPost
if (!loading) {
getPost = data.getPost
}
...

I did this and it worked without any error
const postId = props.match.params.postId
const { user } = useContext(AuthContext)
const { loading, data} = useQuery(FETCH_POST_QUERY, {
variables: {postId}
}
)
if (loading){return (
Loading
)}; //this is where i added a lineconst {id,
body,
createdAt,
username,
comments,
likes,
likeCount,
commentCount
} = data.getPost
let postMarkup
and then just define postMarkup and continue like he does.
