我们正在使用Perfex CRM，并试图在其中添加Rest API模块。当我试图创建新的API并添加新用户时，它显示了错误列表。

Severity: Notice
Message: Undefined index: password
Filename: models/Api_model.php
Line Number: 373

Function: require_once

致命错误：无法声明类Firebase\JWT\JWT，因为该名称已在/home/dir/public_html/www.example.com的第22行中使用domain.com/modules/api/third_party/php-jwt/JWT.php on line 22

Severity: Compile Error
Message: Cannot declare class Firebase\JWT\JWT, because the name is already in use
Filename: php-jwt/JWT.php
Line Number: 22

先谢谢你
