How to pass BigInt as an argument type to the query?

[winsoroaks]

Hi all. I am trying to pass an argument that is of BigInt type as a condition to my query but was not successful.

query MyQuery($number: BigInt!) {
  counts(where: { number: $number }) {

im getting

TypeError: Do not know how to serialize a BigInt
    at JSON.stringify (<anonymous>)
    at createRequestBody (index.js:381:32)

i then tweaked my schema for the number to be of type String and make the number to be of type String! in the query. i then ran into

Error: Variable "$number" of type "String!" used in position expecting type "BigInt".

Please let me know if this is the wrong place to ask the question. Thank you.
