---

OS: Android 8.1.0
Security Update Level: April, 5th 2018

The following message has appeared for 2 days:
For input string: “T”

I changed nothing.
After the message appeared I deleted the account and added it again. No improvement.

Hello,

Seems like an invalid input file. Can you please post the (anonymized) contents of the remote resource (just open the URL with a browser and enter your CalDAV user name/password) here and/or send it to play@bitfire.at (PGP key)?

You can also try to validate it with an iCalendar validator.

Hey,

thanks for help.
Seems that I am unable or to stupid to get the remote ressource content. Browser shows me nothing with the link.

icalender validator shows this:

Problem! Found 1 warning
Warnings

Invalid MIME type detected, should be 'text/calendar' (found MIME type 'application/xml; charset=utf-8') near line # 1Reference: RFC 5545 8.1. iCalendar Media Type Registration

Problem! Found 2 errors
Errors

This is not an iCalendar file or URL near line # 1Reference: RFC 5545 3.4. iCalendar Object
Missing VCALENDAR object near line # 1Reference: RFC 5545 3.4 iCalendar Object

Without the file, I can’t say anything about the problem. I strongly suspect that the file is invalid (some problem with the Duration value), but to be sure I’d need the file.

The browser should offer to download the file when you paste the URL into the address bar. You can also use a download manager or something like that. The .ics file can be downloaded like any other file.

Managed to download the file @ home.

Looks a bit short:

Maybe i should contact the email provider.?

@username7773 I guess this could be the problem:

TRIGGER:-P0DTS

RFC 5545 3.3.6:

   dur-value  = (["+"] / "-") "P" (dur-date / dur-time / dur-week)

   dur-date   = dur-day [dur-time]
   dur-time   = "T" (dur-hour / dur-minute / dur-second)
   dur-week   = 1*DIGIT "W"
   dur-hour   = 1*DIGIT "H" [dur-minute]
   dur-minute = 1*DIGIT "M" [dur-second]
   dur-second = 1*DIGIT "S"
   dur-day    = 1*DIGIT "D"

Wouldn’t dur-second = 1*DIGIT "S" mean that your value should be -P0DT0S instead of -P0DTS? This would also explain the parsing error.

Can you try to remove the alarm from the event (in the Web interface) and have a look whether synchronization is working then?

I removed all events from that day (the events were in the past anyway) and the message disappeared.

Thanks for your help.
