customerCreate mutation returning no errors, but isn't creating the customer

[JeffSpurlock]

Hello,

I have this function:

async function customerCreate(email: string, fName: string, lName: string){
  const createCustomerInput = {
        "email": email,
        "firstName": fName,
        "lastName": lName,
        "tags": [
          "{REDACTED}"
        ]
    }
  const createCustomerQuery = `
    mutation customerCreate($input: CustomerInput!) {
      customerCreate(input: $input) {
        customer {
          id
        }
        userErrors {
          field
          message
        }
      }
    }`
  const {data, errors, extensions} = await client.request(createCustomerQuery, {
    variables: {
      input: createCustomerInput
    }
  })
  let obj = {
    data,
    errors,
    extensions
  }
  return obj
}

const newCustomer = await customerCreate("test@test.com", "John", "Doe")
console.log(newCustomer.data)

and then the response is 

{ customerCreate: { customer: null, userErrors: [ [Object] ] } }

I don't understand why the customer is coming back null. Also, if log the userErrors property, it says undefined, and if i log the response.errors property, it also shows undefined. So i'm not getting any errors, but it's clearly not working. 

Any ideas?
