Workflows silently “finish” in 0.7 s if an email event points at an inaccessible DCM

[jensroy]

Environment

• Alteryx 2025.1

• Shared DCMs + email events on scheduled workflows

What happened
When a workflow includes an Email Event that uses a DCM you don’t have access to, it runs in about 0.7 seconds, throws no errors or warnings—and never actually executes any tools or produces output.

How to reproduce

1. Open a workflow with an email event configured to fire “After workflow ends with error,” using a DCM you can’t access.

2. Run the workflow.

3. Note the run time (~0.7 s), zero errors/warnings, and no output (even Browse tools remain inactive).

Investigation & workaround

• Copying everything into a new workflow eliminated the issue.

• Disabling the email event alone did not help.

• Removing the event entirely restored normal execution.

Expected behavior
The workflow should fail (with an error) if an event can’t resolve its DCM, not exit silently. Silent failures bypass our server alerts (we don’t yet monitor sub-second run times or record counts), so this poses a real risk. Sharing this i case it helps other users searching for similar issues.

Below screenshot shows a workflow that finished instantly, but leave no output, not even anything from the connected browse tool which usuall get a record in the message log.
