Typeorm连接终止

Question

我在Postgresql数据库中使用Typeorm。 我正在测试一个运行findOne查询的函数，它将引发以下错误：

{ 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" = $1',
  parameters: [ '52e1da6e-f4e1-41dc-9dcd-22679c4265e4' ] }

当我查看postgres日志时，会看到以下内容：

LOG:  unexpected EOF on client connection with an open transaction

为什么我要终止连接？

Answer 1

在遍历代码之后，我发现我在父函数之一中缺少异步等待。 因此，在我的findOne查询之前调用了关闭数据库连接的afterAll块。 添加缺少的等待后，此问题已修复。
