Vercel部署Nuxt调用Octokit出现ERR_OSSL_UNSUPPORTED错误求助

使用Nuxt框架（Nitro作为后端）开发GitHub App安装回调接口，功能是将用户数据导入数据库。该GitHub App部署在Vercel平台，本地私钥配置方式与生产环境一致，且已多次验证密钥有效性，推测问题与Octokit相关。

生产环境配置 #

• Node.js ^20

触发错误的代码 #

const { data: installation } = await octokit.rest.apps.getInstallation({
  installation_id: installationId
})

生产环境错误日志 #

}

已尝试的解决方案 #

• 配置环境变量NEPTUN_GITHUB_APP_PRIVATE_KEY为带引号的私钥字符串，或添加换行符转义格式
• 在代码中使用process.env.NEPTUN_GITHUB_APP_PRIVATE_KEY?.replace(/\n/g, '\n')处理换行
• 设置环境变量NODE_OPTIONS=--openssl-legacy-provider

补充：设置legacy provider后的崩溃日志 #
