ValidationPipe transform does not work when Query() uses dto?

[coarse osprey]

async index(@Query() dto: AuthLogin) {
   return "somethins"
}

export class AuthLogin {
  @IsString()
  @ApiProperty({
    description: '支持的登陆类型',
    required: true,
    default: 'google-oauth2',
    type: 'string',
  })
  type = 'google-oauth2'

  @IsString()
  @ApiProperty({
    description: '回调到前端的地址',
    required: false,
  })
  callbackUrl: string

  @IsBoolean()
  @ApiProperty({
    description: 'UI 登陆方式',
    required: false,
    default: false,
    type: 'boolean',
  })
  prompt = false
}

app.useGlobalPipes(
    new ValidationPipe({
      transform: true,
      transformOptions: {
        enableImplicitConversion: true,
      },
    }),
)

@IsBoolean does not convert values

does not seem to handle the case where the metatype is class.

Query and URL params always come in as strings. You can set enableImplicitTransform to true and it should transform for you

  app.useGlobalPipes(
    new ValidationPipe({
      transform: true,
      transformOptions: {
        enableImplicitConversion: true,
      },
    }),
  )

I have done so, but still no conversion

Dang. Class-transformer just doesn't have the proper metadata then. You can force it with @Tranform(({ value }) => JSON.parse(value))

It works, maybe there should be a note about this in the documentation, I tried to find answers in google and github issuse but had some problems with both.

I know I've answered this on stack overflow before
