Has anyone worked with apollo graphql studio, in regards to DateTime and Date? I can't pass it as a string, guess this is a missing feature not 100% any ideas?

Are you passing an ISO string?

Nothing atm @Ryan

Passing this should work:

2021-11-03T00:00:00.000Z

.

@Ryan that doesn't work either, i've tried it 😞

You’re passing the correct argument here? Prisma is saying that you have provided

null

.

correct, however my graphql dto on the resolver has a type of

Date

which if it's not

Date

it will return null

Yes but in Prisma, you still need to pass an entire date, either the

Date

object or the ISO string. So you would need to have the

DateTime

scalar setup in GraphQL

found the issue ryan, it was my scalar was returning null but changed to:

import {
  CustomScalar,
  Scalar,
} from '@nestjs/graphql';
import { Kind } from 'graphql';

@Scalar('Date', () => Date)
export class DateScalar implements CustomScalar<string, Date> {
  public description = 'Date custom scalar type';

  public parseValue(value: string): Date {
    return new Date(value); // value from the client
  }

  public serialize(value: Date): string {
    return new Date(value).toISOString(); // value sent to the client
  }

  // eslint-disable-next-line @typescript-eslint/no-explicit-any,@typescript-eslint/explicit-module-boundary-types
  public parseLiteral(ast: any): any {
    if (ast.kind === <http://Kind.INT|Kind.INT>) {
      return new Date(ast.value);
    }

    return new Date(ast.value).toISOString();
  }
}
