You may not be facing this error anymore, but just someone encounters the error.
I am using v 4.2.0.
I followed the tutorial below and got the same error.
# Strapi.js Crash Course | Headless CMS Traversy Media
I was sending data like this as in the tutorial but got the error.
{
"title": "Test product",
"description": "test product description.",
"price": 99.99,
"qty": 20
}
Solved the error with this.
{
"data": {
"title": "Test product",
"description": "test product description.",
"price": 99.99,
"qty": 20
}
}
