TypeError: Argument 3 passed to OC\Activity\Event::setObject() must be of the type string, null given, called in /var/www/html/apps/deck/lib/Activity/DeckProvider.php

For some time, the following error appears when the cron job is called. After that, emails will no longer be sent from the App Activity.

Deck: 0.5.2
NC: Version: 15.0.5.3
PHP: 7.2.15

I suspect that the mail handling is not working properly in the app deck. This is only in NC version 15. NC 14 was still fine.

When i use "sudo -u www-data php -f /var/www/html/occ activity:send-mails" the following message appears:
An unhandled exception has been thrown:

can confirm

PLUS

Workaround:

1. deactivate the Deck app

2. use said occ activity:send-mails

This is written in that Mail:
` * stack_create (Today at 9:00 PM)

• card_create (Today at 9:00 PM)
• card_user_assign (Today at 9:00 PM)`

The Stack card and user had different names. (looks like variables in a mail to me..)

3. reactivate the app

4. do some card and stack things

5. use said occ activity sendmail...

This is writtten in that email:

` * ymybe has created card agoodnameforacard in stack agoodnameforastack on board agoodnameforaboard (Today at 9:02 PM)

• ymybe has assigned ymybe to card agoodnameforacard on board agoodnameforaboard (Today at 9:02 PM)`

i think it happends during board creation because everything else didnt throw of the email notifications.

after i received mails.. dont know what happend in step two but i "cleared the air" apparently..

Good luck.
(nc15,php-fpm7.3.2,apache2.4.38,mariadb10.3.13,smptLoginViaSsl)

Another confirmation here.
@ymybe : The workaround works for one time only and while the deck app is disabled. Re-enabling the app makes the occ activity:send-mails command to fail.

Edit: Since it has to do with variables I have to say that I use greek characters in e.g. the card name, the board name etc.

@alexport78 True. everytime you create another board which sends an activity email the notification emails go back to fail. :/

@PpaiSanchez Can you maybe sent me the entry in your database for the failing activity queue entry: OC\Activity\Event->setObject('deck_board', 8, NULL)

You can obtain the relevant data with the following sql query:

select * from oc_activity_mq where object_type='deck_board' and object_id = 8;

@juliushaertl I can send you mine (I have similar error, even ID matches): oc_activity_mq.sql.zip

[rob006]

I was able to temporary fix my mail queue by removing these two records:

(89, 1552767091, 1552770691, 'deck', 'rob006', 'deck', 'board_create', '{"author":"rob006"}', 'deck_board', 8),
(163, 1553011574, 1553015174, 'deck', 'rob006', 'deck', 'board_update_title', '{"author":"rob006","before":"Stack Overflow","after":"Stack Exchange"}', 'deck_board', 5);

Both reported Undefined index: board error.
