Express TS导入Vite React共享ES6包遇导出语法错误排查

我尝试通过GCloud npm仓库中的共享库，在Express TypeScript后端与Vite React前端之间共享通用zod模型和JS函数。共享库在前端运行完全正常，但后端持续报错。

注：ResponseErrorModel在后端可正常工作，但PatientModel和LoginFormModel无论怎么调试都无法运行，已经花了10小时排查各种相关方案。

试过的方案及遇到的问题：

• 若在后端package.json中添加type: module或commonjs配置，错误会消失，但全栈应用无法正常运行，出现LoginRequest.ts:4 POST http://localhost:8080/api/login 500 (Internal Server Error)错误
• 已尝试后端package.json和tsconfig中所有ES/Common相关的配置组合，以及入口文件（index.ts与index.json）的不同设置
• 试过export * from ./forms/LoginModel直接导入LoginFormModel，也试过改用{LoginModel}的方式导入

错误信息："Unexpected Token 'export'"
