Some users unable to post reminders with custom emoji

Issue Summary:
On May 18, 2023 from 12:50 PM PDT to May 22, 2023 07:35 AM PDT, some users found that channel reminders containing emojis couldn't be sent.

We determined that a recent change in code added a property that was invalid in the reminder creation schema, which caused reminders to be rejected upon sending.

Once we reverted the change, the issue was resolved for affected users.

We've resolved the issue with reminders that include custom emoji, and a fix is rolling out now. It will take a little while for the fix to address each affected reminder, but we expect that your reminders will be restored by the next scheduled reminder occurrence.

If you'd prefer to fetch the fix immediately, you can delete the affected reminders and set them up again. Please follow these steps to delete an existing reminder:

1. Open the channel where the reminder was set up.
2. Use the "/remind list" slash command.
3. Find your reminder in the list that appears and click "Delete".
4. Set your reminder up again.

Thank you for your patience while we worked to resolve this. If you have any further trouble, please let us know at
