Typeorm 连接终止

Question

我正在将 Typeorm 与 postgresql 数据库一起使用。我正在测试一个运行 findOne 查询的函数，它抛出以下错误：

{ QueryFailedError: Connection terminated
    at new QueryFailedError (/Users/juanjosegutierrez/projects/banking-server/node_modules/typeorm/error/QueryFailedError.js:27:28)
    at Query.callback (/Users/juanjosegutierrez/projects/banking-server/node_modules/typeorm/driver/postgres/PostgresQueryRunner.js:212:38)
    at Query.Object.<anonymous>.Query.handleError (/Users/juanjosegutierrez/projects/banking-server/node_modules/pg/lib/query.js:142:17)
    at process.nextTick (/Users/juanjosegutierrez/projects/banking-server/node_modules/pg/lib/client.js:59:13)
    at process._tickCallback (internal/process/next_tick.js:61:11)
  message: 'Connection terminated',
  name: 'QueryFailedError',
  query:
   'SELECT "Contact"."id" AS "Contact_id", "Contact"."type" AS "Contact_type" FROM "contacts" "Contact" WHERE "Contact"."id" = ',
  parameters: [ '52e1da6e-f4e1-41dc-9dcd-22679c4265e4' ] }

当我查看我的 postgres 日志时，我看到以下内容：

LOG:  unexpected EOF on client connection with an open transaction

为什么我的连接会被终止？

Answer 1

单步执行代码后，我发现我在其中一个父函数中缺少异步等待。因此，我的关闭数据库连接的 afterAll 块在我的 findOne 查询之前被调用。添加缺失的 await 后问题得到解决。
