Issue summary:
On February 29, 2024 from 1:28 PM PST to around 4:36 PM PST, users were unable to create or update some workflows.

We determined that a recent code change had inadvertently introduced a logic problem, resulting in errors for workflows that used event triggers. We reverted this code change. However, rolling back reintroduced a separate issue that we'd resolved earlier in the day.

We prepared a tailored revert to roll back the code causing the workflow problem while also including the fix for the previous issue. This second revert resolved both problems, restoring full functionality to Slack.

Thank you for being patient with us.

9:48 PM PST

We've restored full functionality to the workflow tool for all users.

No steps are required to see this fix in your workspaces.

We're sorry for the disruption this caused.

5:08 PM PST

We're continuing to work on restoring workflow functionality for all users.

We initially rolled back what we thought was the problematic code, though this didn't create positive change to the issue at hand.

We're looking into another possible solution and will report back as soon as we have more news to share.

4:33 PM PST

We're still actively working on getting this fixed, but we don’t have any new information to share at this time. Thank you for your continued patience.

3:16 PM PST

We have determined that this issue is specific to workflows that contain event triggers. We've discovered the root cause and are working to resolve this as quickly as possible. Thank you for bearing with us in the meantime.

2:47 PM PST

We're currently investigating an issue that is preventing users from creating and updating workflows. We'll be back with another update when we know more, and we apologize for the inconvenience in the meantime.
