VS Code更新后Azure Web App部署报SyntaxError问题排查及解决

更新（2023年5月18日） #

将Azure应用设置中的WEBSITE_NODE_DEFAULT_VERSION从6.9.1修改为本地使用的Node.js 18版本后，部署成功。

WEBSITE_NODE_DEFAULT_VERSION

问题描述 #

不清楚部署失败的原因。此前VS Code从1.65版本升级到1.66版本时就遇到过相同问题，只能停留在1.65版本；此次升级到1.78.2后问题重现。
尝试降级到2023年3月版VS Code重试部署，但失败情况依旧（注：尝试部署时1.78.2版本仍在运行，不确定是否有影响）。

部署输出信息如下，无法理解其含义也不知道如何调试：已开启Azure应用日志，但部署时日志流无内容；打开Kudu（*.scm.azurewebsites.net）查看文件，未找到有效信息，可能是对Kudu调试用法不熟悉。

补充更新 #

查看记录发现，2022年4月8日使用VS Code 1.66.1时也曾遇到相同部署失败问题，降级到1.65.2后恢复正常。

疑问 #

是否存在VS Code、Azure与部署的Web App之间的兼容性问题？已确认Web App服务和应用均使用.NET 6，也重启了Mac和VS Code，还能通过哪些方式排查或重置相关设置？
