Jackett: [mejortorrent] Sequence contains no elements (Config)

Created on 3 Jul 2019  路  24Comments  路  Source: Jackett/Jackett

Hey! When trying to add indexer "mejortorrent" it gives me the " An error occured while updating this indexer. Sequence contains no elements" error.
I can browse for "https://www.mejortorrentt.org/" which is the "site link" for this tracker and download torrents on them web site.

Log for this error:
System.InvalidOperationException: Sequence contains no elements

I know it is duplicated. But you did close them post because they did give no details at all. I think I did give some details for you to help me :D

This issues:

[mejortorrent] Sequence contains no elements (Config) #5776

They are closed because they are duplicated. The problem is not solved.
When will they solve the problem?

auxilig picture auxilig on 4 Aug 2019

problem will not be solved until a volunteer c# developer contributes.
BTW I am not a c# developer and this indexer written in c# is way too complicated for my paltry c# skills.
Any volunteers out there? Feel free to raise a PR and contribute.

The problem persist for URL such as https://mejortorrent1.net/ since http://www.mejortorrentt.org/ which works and does not return this problem, donesn't return .torrents but .vsb instead

Seems like all torrents size is 16GB or 1.5GB no matter what real size they are.
May this be mejortorrent's fault?

I don't know if I should have opened a new issue or not...

josopu picture josopu on 18 Mar 2020

@josopu

the site's search results page does not have the size.
but if the indexer leaves size as null or 0B then some apps will not download
so we provide defaults.
