Items Query responding with "Unexpected token"

Hi,
Similar to this question: Items Query responding with error

I have the exact same error; for example (on version 2023-07)

query {
  boards (ids: 3553135069) {
    items {
      id
      name
      column_values {
        id
        title
        value
      }
    }
  }
}

Returns:

{
  "errors": [
    {
      "message": "Unexpected token 'u', \"upstream r\"... is not valid JSON",
      "stack": "SyntaxError: Unexpected token 'u', \"upstream r\"... is not valid JSON"
    }
  ]
}

This query just ran successfully this morning, 10 minutes later the same query doesn’t work.

Hello @rogerlp and welcome to the community!

I hope you like it here :muscle:

What happens if you use a limit for the items? Do you still get the error?

query {
  boards (ids: 3553135069) {
    items (limit: 10, page: 1) {
      id
      name
      column_values {
        id
        title
        value
      }
    }
  }
}
