Every time you use webdav to sync photos, an error will be reported，

Caddy server is windows 10. The phone uses photosync+webdav to synchronize photos, and an error will be reported every time a photo is synchronized.

Error message： Cannot create a file when that file already exists

Tip: The error log will be output, but it does not affect the use

Caddyfile：

{
	order webdav before file_server
}

:7001 {
	webdav {
		root D:/_data
		prefix /
	}
}

error.log：
