Number converting to string

[gabrielwbenatti]

I'm new using Express JS, and I have a doubt

I'm making an API and i'm using Prisma ORM.
For example, I have a table named "purchases" and some decimal type columns. The return from theese database columns are numerics (as espected) but when my API is gonna response, thesse columns are turned as string.

My app is using express.json() to convert, but I don't know if I need to change another thing

Database return

API response
