error when trying to call aggregate function

[thormengkheang]

I can query customersConnection via GraphQL playground but I can't access vai code like in the document https://www.prisma.io/docs/prisma-client/basic-data-access/reading-data-JAVASCRIPT-rsc2/#aggregations

await prisma.customersConnection().aggregate().count()

got an error like this

{
  "data": null,
  "errors": [
    {
      "message": "prisma.customersConnection is not a function",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "customers"
      ]
    }
  ]
}

I have the same issue with Prisma-binding

const bookCount = await prisma.query.usersConnection().aggregate().count();

console.log(bookCount)

TypeError: prisma.query.usersConnection(...).aggregate is not a function
