Cannot read property 'isInt' of undefined

I'm running a very simple graphql query via the graphql cli tool.
I get the error: "Cannot read property 'isInt' of undefined".
Any idea why?

query test($name: String) {
Person(name: $name) {

Hello Eric, I see you're using a function with parameters are you correctly passing those in via the graphiql tools? You might want to try manually passing the parameter to ensure that it's working that way.

I invoke the cli tool as follow:
graphql query test "Joe smith"

It's working fine using the grahpql service in a browser.

What does your GraphQL Schema look like? I'm assuming:

type Person {
firstName: String,
lastName: String

If that's the case you need to have a corresponding variable in your query, with what you currently have it I think it would be:

query test($name: String){
Person(first: $name){

I'm not sure your schema is quite matching up with your query.

The query matches the schema. It works using the graphql service in a browser but not with the cli tool. It seems something is not configured properly with the cli tool. That's the stacktrace I get:

How are you passing the variable? Here's an example from a project I've worked on so it won't match your query of course:

But it's the proper way to pass the variable. If you feel like you can you might share, your type definition and if you're using Neo4j-graphql-js as well.

Thanks for your replies. I figured it out. I needed to clear the npm cache and reinstall core-js. It's working now

Glad you got it working.
