Error: Schema engine error: ERROR: password authentication failed for user '', prisma, postgresql

I have created Postgres database with Vercel, and when trying to migrate with command npx prisma migrate dev i receive:

Environment variables loaded from .env
Prisma schema loaded from prismaschema.prisma       
Datasource "db": PostgreSQL database "verceldb", schema "public" at "ep-curly-resonance-50034155.eu-central-1.postgres.vercel-storage.com:5432"

Error: Schema engine error:
ERROR: password authentication failed for user ''

I’m weak in the backend and don’t know how to help you understand the problem, so I’m leaving these prisma and .env codes in case you need them:

schema.prisma:

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "postgresql"
  url = env("POSTGRES_PRISMA_URL") // uses connection pooling
  directUrl = env("POSTGRES_URL_NON_POOLING") // uses a direct connection
}

model Form {
  id Int @id @default(autoincrement())
  userId String
  createdAt DateTime @default(now())
  published Boolean @default(false)
  name String
  description String @default("")
  content String @default("[]")

  visits Int @default(0)
  submissions Int @default(0)

  shareURL String @default(uuid())
  FormSubmissions FormSubmissions[]
}

model FormSubmissions {
  id Int @id @default(autoincrement())
  createdAt DateTime @default(now())
  formId Int
  form Form @relation(fields: [formId], references: [id])

  content String
}
