Error when creating a calendar object: "A calendar object on a CalDAV server may only have components with the same UID" #1264

Open sven-ahrens opened 4 years ago

Hey there,

I'm at a stage of my application where I wanted to test if thinks work out. So I've been trying to create a calendar object by uploading the content of an .ics file. This ics file is exported from my macOS computer.

By doing so, I get the following error message:

3.2.2 Sabre\DAV\Exception\UnsupportedMediaType Validation error in iCalendar: A calendar object on a CalDAV server may only have components with the same UID.

I've also validated this on https://icalendar.org/ but there is no error at all.

This is the content of my .ics file

In CalDAV, every event must be uploaded separately with its own PUT request. Exports often have more than 1 event, so the server will reject this. If you are comfortable with PHP, the vobject package has a way to split up these files in multiple files.

But it's also something you could potentially do manually with such a simple object. Note that METHOD:PUBLISH should also be removed before you PUT.
