I am attempting to set up a Scheduled Reminder for Scheduled Activities (CiviCRM 5.20.2/Drupal 7).
I have a Scheduled Reminder set up as follows: Image of Schedule Reminders screen showing Phone Call reminder

This is setup to send to the Activity Assignees, 0 hours before a Scheduled Phone Call activity. It is enabled, and has a simple email message.

Under Scheduled Jobs, I can see that "Send Scheduled Reminders" (Job.send_reminder) is enabled, is running always, and the logs say it is successful.

Finished execution of Send Scheduled Reminders with result: Success (1)

If I then create an Activity of type Phone Call, set its status to Scheduled, set the time to 30min in the future, and assign it to myself, I will immediately get a system generated Activity Summary email. In 30min time I will not get a reminder from the Scheduled Reminder, with the template I defined.

Can anyone tell me why, or tell me where to look for more information? Are there logs which will show me if the reminder is actually being triggered, or if an attempt is made to send the email?

  • You could try changing it to 0 hours AFTER the activity time and see if that makes a difference? Commented Apr 3, 2020 at 8:14
  • Thanks for the suggestion - unfortunately it still didn't trigger. I also tried setting repetitions, but they also didn't trigger. Commented Apr 6, 2020 at 3:40
  • OK, I have discovered the civicrm_action_log which I can view using phpmyadmin. All the reminders are visible there - all have an error "Failed to send message". This looks email related. Commented Apr 6, 2020 at 23:56
  • Continuing to debug - after switching to sendmail from direct SMTP to Amazon SES, we have discovered that the emails are being sent, but apart from the "To:" field, they are completely blank. No subject, no body. Has anyone encountered this? Commented Apr 8, 2020 at 23:10

OK, answering my own question after much investigation. This was a bitnami civiCRM stack and the crontab to run Job.execute was running as the bitnami user (our error), but needed to run as daemon. That is documented on bitnami's site: https://docs.bitnami.com/bch/apps/civicrm/configuration/configure-scheduler/

Strange behaviour as a result of this - cron seemed to be running fine, but it clearly didn't have permissions to send emails.
