GraphQL/APOLLO – Cannot query field “field_name” on type “Query”

I am trying to make a query like this in the latest apollo/server 4.9 and graphqlClient – 3.7 like below:

const USER_DATA = gql`
query getUserData($subdomain: String!) {
getUserData(subdomain: $subdomain) {
  _id
  full_name
  email
  valid_complex_password
  projects {
    _id
    image_url
    title
    description
    street_address
    city
    province
    country
  }
 }
}

but keep getting this:

{
"errors": [
    {
        "message": "Cannot query field "getUserData" on type "Query".",
        "locations": [
            {
                "line": 2,
                "column": 3
            }
        ],
        "extensions": {
            "code": "GRAPHQL_VALIDATION_FAILED",
            "stacktrace": [
                "GraphQLError: Cannot query field "getUserData" on type "Query".",
                ......
            ]
        }
    }
]

}

This same query used to work fine with older version of apollo server/client and graphql. Post upgrade it started breaking without any changes to schema etc.

Anything that needs to be changed in the way this is queried or I am missing something?
