Message reminders not triggering as expected

Message Reminders Not Working Due to Disabled System Bot

Overview

Mattermost’s message reminder feature allows users to set reminders on specific posts after a chosen time delay. These reminders are sent via the system bot.

If the system bot becomes disabled — either manually or because the associated user account is deactivated — message reminders will no longer be delivered.

How to Identify the Issue

If reminders are not being sent, check the server logs for an error similar to the following:

{"timestamp":"2023-10-20 11:35:00.008 -07:00","level":"error","msg":"Failed to get system bot","caller":"app/post.go:2121","error":"SqlBotStore.Get: Bot does not exist., resource: Bot id: <bot id>"}

This log message indicates that the system bot could not be found or is inactive.

Solution

To restore message reminder functionality:

• Re-enable the system bot by activating the associated user account if it was deactivated.
• Refer to the bot accounts documentation for more details on managing bot users in Mattermost.

Once the system bot is active again, message reminders should resume as expected.
