Issue

After an upgrade to 8.7.1 I get the following error when executing cron from the command line:

sudo -u www-data php cron.php 

PHP Fatal error:  Uncaught Error: Call to a member function modify() on null in /var/www/crm/public/legacy/modules/Reminders/Reminder.php:266

Hey!
Thank you for being in touch.
I've given this a try locally but have not yet been able to replicate, I'm afraid

Could you share some more info on this scenario so I can try to closer match your setup/steps?

ie:

• Does this happen for every Call/Meeting, or just specific ones?
• On the Meetings/Calls with pending Reminder Emails, do the invitees have valid Email addresses?
• On the Meetings/Calls with pending Reminder Emails, do the invitees have non-UTC timezones or Custom Date/time Formats?
• Do you see anything in the SuiteCRM Error logs for this? (ie: /public/legacy/SuiteCRM.log or /logs/prod/prod.log)
• Which PHP Version are you using when running cron?
• Did you have any issues during upgrade? (ie: When running both upgrade and upgrade-finalize commands?)

Thank you again!
