Hi! How you serialize one bigint property? I have installed the

graphql-scalars

package and I'm using like this

Copy code

@Field(() => GraphQLScalars.BigIntResolver, {
    nullable: true
  })
  lte?: bigint | undefined;

But when it's not null I recieved an error

Copy code

"message": "Do not know how to serialize a BigInt"

Any approach to fix it or how serialize it properly?

This happens since I have upgraded prisma to v4, in last 3.x.x version it was working without any problem.

Previously It was working with this exposed model to graphql

Copy code

export class EntityGroupBy {
    @Field(() => String, {
        nullable: false
      })
      name!: string;

    @Field(() => Int, {
    nullable: false
    })
    numCount!: number;
}

And it's a queryRaw, I have no defined any as bigint. Have you changed the default type for numbers in v4?

Copy code

select ct."name", count(*) "numCount" 
from "Contract" c 
inner join "ContractType" ct on c.type=ct.id 
group by ct."name"

https://www.prisma.io/docs/guides/upgrade-guides/upgrading-versions/upgrading-to-prisma-4#upgrade-path-6 this outlines the type changes as part of v4
