使用postgres和npm运行docker容器会产生此错误，同时分别运行它们 （npm和docker）没有。这里似乎是什么错误？
我的docker-compose.yml：
$oauth_client_id = '***';
$oauth_client_secret = '***';
// If you're using DEVELOPMENT TOKENS, you MUST USE SANDBOX MODE!!! If you're in PRODUCTION, then DO NOT use sandbox.
$sandbox = true; // When you're using development tokens
//$sandbox = false; // When you're using production tokens
// This is the URL of your OAuth auth handler page
$quickbooks_oauth_url = 'http://www.***.com/quickbooks/docs/partner_platform/example_app_ipp_v3/oauth.php';
// This is the URL to forward the user to after they have connected to IPP/IDS via OAuth
$quickbooks_success_url = 'http://www.***.com/quickbooks/docs/partner_platform/example_app_ipp_v3/success.php';
// This is the menu URL script
$quickbooks_menu_url = 'http://www.***.com/quickbooks/docs/partner_platform/example_app_ipp_v3/menu.php';
// This is a database connection string that will be used to store the OAuth credentials
// $dsn = 'pgsql://username:password@hostname/database';
// $dsn = 'mysql://username:password@hostname/database';
$dsn = 'mysqli://***_intuit:***@localhost/***_quickbooks';
// You should set this to an encryption key specific to your app
$encryption_key = '***';
// Scope required
$scope = 'com.intuit.quickbooks.accounting ';
// The tenant that user is accessing within your own app
$the_tenant = 12345;
我检查过的东西：
postgresql.conf和pg_hba.conf接受连接。
数据库凭据正确。
Db正在运行
