Hyperledger Fabric Samples部署：CA证书文件缺失致应用启动失败

已完成Asset Transfer Basic的TypeScript和Go版本链码部署，但执行npm start启动应用时出现证书文件缺失错误，具体提示找不到指定路径的cert.pem。完整执行输出如下：

asset-transfer-basic@1.0.0 start
node dist/app.js

channelName: mychannel
chaincodeName: basic
mspId: Org1MSP
cryptoPath: /home/gokulalex/Code/fabric/fabric-samples/test-network/organizations/peerOrganizations/org1.example.com

peerHostAlias: peer0.org1.example.com

******** FAILED to run the application: [Error: ENOENT: no such file or directory, open '/home/gokulalex/Code/fabric/fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/signcerts/cert.pem'] {
errno: -2,

}

排查步骤： #

• 验证文件路径与实际文件：前往报错的路径/home/gokulalex/Code/fabric/fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/signcerts/，确认是否存在cert.pem，部分场景下证书文件名可能为User1@org1.example.com-cert.pem，若存在此类文件，可修改应用配置中的certPath指向正确文件名，或创建软链接将其命名为cert.pem
• 重新生成用户身份文件：进入test-network目录，执行./organizations/fabric-ca/registerEnroll.sh org1脚本，重新生成Org1的User1身份相关证书与密钥文件，该脚本会自动在对应目录生成标准命名的证书文件
• 检查应用配置：确认应用的配置文件（如connection.json或环境变量配置）中certPath的路径是否完全正确，注意目录层级、大小写是否与实际文件系统匹配
• 权限检查：执行ls -l /home/gokulalex/Code/fabric/fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/signcerts/查看文件权限，若当前用户无读取权限，执行chmod +r <对应证书文件路径>添加读取权限
