question: how to validate array.length?

[toknT]

I am using nestjs+gql it's the code

@InputType()
export class InsertSessionsInput {
  @Max(1000, { message: 'limit 1000 items' })
  @Field(() => [InMemoSession])
  sessions: InMemoSession[];
}

The problem:

it check the length of object.toString() not the length of array,

Use these:

@IsArray()
@ArrayMinSize(1)
@ArrayMaxSize(1000)
