example schema

taxAmount!: Decimal | null;

and this sample code to insert db

 prisma.taxAmount = model.taxAmount ? parseFloat(model.taxAmount) : undefined;

and this error

Type 'Decimal | 'undefined' | null' is not assignable to type 'Decimal | null'.

Type 'undefined' is not assignable to type 'Decimal | null'.ts(2322) (property) DeliveryDetailsPrisma.taxAmount: Decimal | null

how to fix it ?

CodePudding user response：

Are you sure you can't do with assigning null instead of undefined? The taxAmount field seems to be expecting Decimal or null, not undefined. Moreover, Null and undefined have separate meanings in the context of Prisma.

If you try the following instead, it should work fine.

prisma.taxAmount = model.taxAmount ? parseFloat(model.taxAmount) : null;
