部署到 Heroku 后的 Prisma 迁移问题

问题描述

我有一个用 NextJS 编写的应用部署到 Vercel，并在 Heroku 上启动了 Postresql。

之前我使用 MysqL，然后将配置更改为 Postgresql。我已使用 npx prisma migrate save --schema ./prisma/schema.prisma --experimental

将表部署到 Heroku Postgresql

现在，我在执行 npx prisma migrate up --schema ./prisma/schema.prisma --experimental

时遇到了问题

我得到的错误是：

Changes to be applied:

model TableA {
  id Int @default(autoincrement()) @id
  ...skipped columns...
}

model TableB {
  id Int @default(autoincrement()) @id
  ...skipped columns...
}

Checking the datasource for potential data loss...

You can get the detailed db changes with yarn prisma migrate up --experimental --verbose
