prisma introspect generate invalid model - sql

Question

Prisma version : ^2.26.0
Prisma/client : ^2.26.0
#relation error msg in : Error parsing attribute "#relation": The type of the field userId in the model posts is not matching the type of the referenced field id in model users.
Why prisma created invalid model or something wrong with my code after i run npx prisma introspect?
It cause cannot to enter the prisma studio since those error in my code.
Any solution or thought could share to make me know better for this?
Below is my sql:
-- Create a custom type
CREATE TYPE "user_role_enum" AS ENUM ('user', 'admin', 'superadmin');
-- Create a table
CREATE TABLE "users"(
"id" BIGSERIAL PRIMARY KEY NOT NULL,
"name" VARCHAR(255) NOT NULL,
"email" VARCHAR(255) UNIQUE NOT NULL,
"role" user_role_enum NOT NULL DEFAULT('user')
);
-- Create a table
CREATE TABLE "posts"(
"id" BIGSERIAL PRIMARY KEY NOT NULL,
"title" VARCHAR(255) NOT NULL,
"body" TEXT,
"userId" INTEGER NOT NULL,
FOREIGN KEY ("userId") REFERENCES "users"("id")
);
-- Create data
INSERT INTO "users" ("name", "email", "role")
VALUES('John Doe', 'john#email.com', 'admin'),
('jane Doe', 'jane#email.com', 'admin'),
('Ahmed Hadjou', 'ahmed#hadjou.com', 'user');
INSERT INTO "posts" ("title", "body", "userId")
VALUES('Hello World!!', 'Hey guys, I see a rainbow through this prisma :D', 1),
('So do I', 'It looks cooool!!!', 2),
('It does', 'Yeahhh', 1);
Generate for model from prisma introspect
model posts {
id BigInt #id #default(autoincrement())
title String #db.VarChar(255)
body String?
userId Int
users users #relation(fields: [userId], references: [id]) // Error parsing attribute "#relation": The type of the field `userId` in the model `posts` is not matching the type of the referenced field `id` in model `users`.
}
model users {
id BigInt #id #default(autoincrement())
name String #db.VarChar(255)
email String #unique #db.VarChar(255)
role user_role_enum #default(user)
posts posts[] // error in here
}
enum user_role_enum {
user
admin
superadmin
}
