Could not save the timer. Check the log

[Penfold]

Hi,

Firstly thanks so much for creating Next PVR it's a fantastic bit of software.

I have Kodi Matrix and Next PVR V5 on a windows 10 PC with a 4ch TBS Freesat receiver card

99.9% of the time it works flawlessly but today I am trying to record a program later on in the day by selecting it on the guide in Kodi and pressing record on my remote, or by using the mouse/keyboard to record.

The error I get is as follows:

Error
Could not save the timer. Check the log for more information about this message

I have had a look in the logs from Next PVR and I can see the request but it fails at

2021-03-17 17:32:47.305 [ERROR][34] System.FormatException: The header contains invalid values at index 0: '<null>'
  at Microsoft.Net.Http.Headers.HttpHeaderParser`1.ParseValue(StringSegment value, Int32& index)

  at Microsoft.AspNetCore.Mvc.ControllerBase.File(Stream fileStream, String contentType)
  at NPVR5.Controllers.ServicesController.HandleServiceRequest(String body, String contentType)


I have attached the logs in a ZIP

Has anyone got an Idea what could be wrong?

Kind regards

Andy

Are you running the Dec NextPVR update it is required for Matrix? I do see an issue but I would need the Kodi debug logs and please post Kodi support questions in the Kodi sub forum here

Hi thanks for the reply
Sorry for posting in this section.
Yes I am running the Update from DEC as I only installed this about a month ago.
Are these the logs you are looking for?

Thanks those are standard logs not debug logs. Turn on debug logging https://kodi.wiki/view/Log_file then duplicate the problem and post the kodi log again.

Hi,

Thanks for the info. Will do that when the problem arises again, as its not happening now.

Ok I can explain the problem. There was a change in Matrix in that Kodi doesn't reload the EPG on startup (but it will after a default 2 hour period after the last one) that is the reason for potential EPG problems. I thought I put in a change to help mitigate this but it doesn't seem to work.

You seem to be requesting a future recording for Channel 4 but NextPVR is telling Kodi there are no listings in the time that was requested so there is no program to linkto in the guide. Are you by chance asking for a future date that is not yet in the guide?

@sub if you see a reason why this might return no listings if they exist let me know.

@sub if you see a reason why this might return no listings if they exist let me know.

I don't remember seeing any reports of it not returning listing. I'd have to assume it doesn't have any listings at that specific time requested. (maybe ATSC epg user, with only had a few hours at a time?)

Thanks sub. Andy if the data isn't in the EPG which is what we speculate, you can't create a future recording via the guide, you'd need to create a manual rule or an anytime rule based on the current show.

Hi
Thanks for the effort you guys put in to this minor problem.
I cleared the guide data from Kodi and restarted the machine. No problems until now.
I have put the Kodi log on for you.
I have now tried to record a program in around 2 hours time and it gives me the error. The program shows in the guide.
I also tried to make the same recording from other front end systems connected and the same error message.
Interesting to note that following your comments I went to the Next PVR web app and the EPG has not populated although it is in Kodi.
Looks like the EPG in Next PVR doesn't match Kodi or the other way round.

I will have a look at the EPG settings and see if there is an error in the settings.

If it is not in the web app but is in Kodi the does indicate a problem and explains the issue completely and I understand the problem better now. At the beginning of the nrecord.log.3 there is xml from the OTA guide and it is logged because that load is failing and we see

2021-03-17 02:45:57.621 [DEBUG][31] Got 0 events

I suspect there is an block of time that sometime makes it to Kodi and sometimes doesn't.

If you look in that xml there is clearly corruption at the end and interestingly the start time goes wonky too in the previous record so that record is bad too.
