Hi Quentin,

I sent you a sample .eml file of one of the emails we are no more able to view.

And today I also would like to let you know that even internal emails are not working. I sent an email to myself and the display is not working, I still get the 'Request Failed' and the email body is not displayed.


Have you been able to narrow the issue ?


Best regards,

Laurent

Could you give me the eml of a mail that doesn't work anymore ? You can send it to [email protected]

Hello,

I am running SOGo on Debian trixie with the nightly builds and since the
latest manual update this week-end I cannot open some of the received emails.
The SOGo interface just shows 'Request failed' but the logs show this:

There is either an issue with the 'WOxElemBuilder' missing or the
'NAME:NSInvalidArgumentException REASON:[NSString+stringWithString:]: NULL
string INFO:(null)'.

This does not affect emails viewed on the mobile phone, they can be viewed
without problems.

Let me know when this is fixed in order to update my SOGo server and be able
to view those emails.
