мой очень простой API prisma GraphQL отлично работает в моей локальной базе данных PostgreSQL, размещенной в Docker. Как только я переключаюсь на свой PostgreSQL, размещенный на DigitalOcean, он перестает работать.

Вот мой код: мои типы:

 const typeDefs = gql`   type Book {  id: ID!  name: String  content: String   }    type Query {   books: [Book!]!   }   type Mutation {   createBook(name: String, content: String): Book!    }  `  

Вот мои решатели:

 const resolvers = {  Query: {  books: (parent, args) =gt; {  return prisma.book.findMany()  },   },    Mutation: {   createBook: (parent, args) =gt; {  return prisma.book.create({  data: {  name: args.name,  content: args.content  }  })  }  } }  

А вот мой файл schema.prisma:

 generator client {  provider = "prisma-client-js" }  datasource db {  provider = "postgresql"  url = env("DATABASE_URL") }  model Book {  id Int @id @default(autoincrement())  name String?  content String? }  

Я попытался сбросить базу данных и т. Д. и т. Д. Ничего не работает.

Вот ошибка, которую я получаю:
