无法解构“db.config.connection”的属性“client”，因为它未定义

Question

无法解构“db.config.connection”的属性“client”，因为它未定义..任何人都可以告诉我哪里出错了..谢谢...

config/database.ts

import path from 'path';
import { fileURLToPath } from 'url';

// Derive __filename and __dirname
const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);
import { DatabaseConfig } from '../src/types/strapi'; 

export default ({ env }: { env: (key: string, defaultValue?: any) => any }): DatabaseConfig => {
  // Resolve the filename with environment variable or default value
  const filename = path.join(
    __dirname,
    '..',
    '..',
    env('DATABASE_FILENAME', path.join('.tmp', 'data.db'))
  );

  // Debugging output
  console.log('Resolved Filename Path:', filename); 
  console.log('DATABASE_CLIENT:', env('DATABASE_CLIENT', 'sqlite')); 

  // Database configuration
  const config: DatabaseConfig = {
    connection: {
      client: env('DATABASE_CLIENT', 'sqlite'), 
      connection: {
        filename: filename, 
      },
      useNullAsDefault: true, 

    },
  };

  // Return the configuration object
  return config;
};

src/types/strapi.d.ts
export interface DatabaseConfig {
  connection: {
    client: string;
    connection: {
      filename?: string;
      host?: string;
      port?: number;
      database?: string;
      user?: string;
      password?: string;
    };
    useNullAsDefault?: boolean;
  };
}

我正在开发一个 Strapi 应用程序..任何人都可以告诉我哪里错了

TypeError：无法解构“db.config.connection”的属性“client”，因为它未定义。

根据我的笔记，我自己解决了这个问题。以下是我会仔细检查以确保其有效的事情。对于上下文，我正在努力设置单元测试。

• 仔细检查您的环境变量。环境中至少需要

  DATABASE_FILENAME=.tmp/data.db

  。
• 您正在使用打字稿，因此在我从here窃取的 setupStrapi 辅助函数中，您将进行一个小更新。

export async function setupStrapi() {
  let instance: Required<StrapiI>;
  if (!instance) {
-    await Strapi().load();
+    await Strapi({ distDir: "./dist" }).load();
    await waitForServer();

    instance = strapi;
  }

  return instance;
}

• 最后插件

  "strapi-plugin-sitemap"

  也导致了这个错误。版本至少需要为 3.2.1。

  "strapi-plugin-sitemap": "3.2.1"
