Broken Prisma query is generated by swagger UI when the query is a nested object

[abrl91]

Is there an existing issue for this?

Current behavior

I have an application written with Nestjs, Prisma, GraphQL, and when I try to make a query with a form of a nested object the query is sent in the wrong format.

For example the API request: GET /api/users

@common.Get()
  @nestAccessControl.UseRoles({
    resource: "User",
    action: "read",
    possession: "any",
  })
  @swagger.ApiOkResponse({ type: [User] })
  @swagger.ApiForbiddenResponse()
  @swagger.ApiQuery({
    type: () => UserFindManyArgs,
    style: "deepObject",
    explode: true,
  })
  async findMany(
    @common.Req() request: Request,
    @nestAccessControl.UserRoles() userRoles: string[]
  ): Promise<User[]> {
    const args = plainToClass(UserFindManyArgs, request.query);

    const permission = this.rolesBuilder.permission({
      role: userRoles,
      action: "read",
      possession: "any",
      resource: "User",
    });
    const results = await this.service.findMany({
      ...args,
      select: {
        id: true,
        createdAt: true,
        updatedAt: true,
        firstName: true,
        lastName: true,
        username: true,
        roles: true,

        profile: {
          select: {
            id: true,
          },
        },
      },
    });
    return results.map((result) => permission.filter(result));
  }

When I log the generated query I get the following output:

{
  "firstName": {
    "equals": "string",
    "in": [
      "string"
    ],
    "notIn": [
      "string"
    ],
    "lt": "string",
    "lte": "string",
    "gt": "string",
    "gte": "string",
    "contains": "string",
    "startsWith": "string",
    "endsWith": "string",
    "mode": "Default",
    "not": "string"
  },

..... and the rest of the query from the where input property

Minimum reproduction code

Steps to reproduce

docker compose -d go to localhot:3000/api

Expected behavior

We can see that is missing the parameter name where at the beginning of the sample. I expected to get:

+ {where: 
{
  "firstName": {
    "equals": "string",
    "in": [
      "string"
    ],
    "notIn": [
      "string"
    ],
    "lt": "string",
    "lte": "string",
    "gt": "string",
    "gte": "string",
    "contains": "string",
    "startsWith": "string",
    "endsWith": "string",
    "mode": "Default",
    "not": "string"
  },
+}

We can see that regarding the skip and take (both type number) the URL generated as expected

I found a solution for how to solve it and I would like to try to add this solution as a decorator to nestjs/swagger and hope someone could guide me on how to test my solution.
