Decimal inconsistency

[rjnkr]

Prisma model

model OperBrandstof {
@@Map("oper_brandstof")

/// @description Prijs per liter van de brandstof
PRIJS Decimal? @db.Decimal(6, 2)
}

The Create DTO looks like

@ApiProperty({
description: "Het bedrag van de tankbeurt om te kunnen factureren",
type: "number", <-- number
format: "double",
required: false,
nullable: true,
})
@IsOptional()
@IsDecimal()
PRIJS?: Prisma.Decimal | null;

The swagger example

{
"PRIJS": 0, <-- number
}

So far so good. It means that I have to provide numeric value for these fields. However when calling the api I need to provide these decimals as string. such as ""PRIJS": "2.01" to make it work. If is specify "PRIJS": 2.01, the error message "PRIJS is not a valid decimal number."

Also for the output the decimal is provided as string. So the interface implementation and the definition are inconsistent. I prefer to work with numbers instead of string. How can I solve this ?
