I hope someone has some new ideas. I've checked it locally a million times and run the query from my graphql endpoint with no problem. BUT everytime I try to push that to Vercel, the build fails with a 400 error. I think I may have tracked it down to $or but can't guarantee it.

typedef:

searchUsers(searchTerm: String): [Users]

resolver:

searchUsers: async (_, { searchTerm }) => {
          try {
            const db = await dbConnect();
            const users = await Users.find({
              $or: [
                { first_name: { $regex: searchTerm, $options: 'i' } },
                { user_name: { $regex: searchTerm, $options: 'i' } }
              ]
            });
            return users;
          } catch (error) {
            // Log the error and any additional information
            console.log('Error in searchUsers resolver:', error);
            console.log('Search term:', searchTerm);
            // log the error stack trace
            console.log('Error stack trace:', error.stack);       
          
          }
        }

query:

export const QUERY_USER_SEARCH_RESULTS = gql`
    query searchUsers($searchTerm: String) {
        searchUsers(searchTerm: $searchTerm) {
            first_name
            last_name
            headline
            user_name
            user_or_real
            profile_url
            photoURL
            firebase_uid
            
        }
    }`

component using apollo nextjs 13 experimental :

const { data, error } = useSuspenseQuery(QUERY_USER_SEARCH_RESULTS,
        {
            variables: {
                "searchTerm": searchTerm
            }
        })
        console.log(JSON.stringify(data) + ' data from server in results component')
    if (error) {
        console.log('Error in getting profile data in User Search: ' + error.message);
        
    }

Is there something going on between Apollo and Next that is causing the build error with Vercel?
