Scheduled Workflow - Skipped Execution for One Day with No Error

Questions

Describe the problem/error/question

I have a scheduled workflow with the following setup custom (cron):

45 7 ** 1-5
and
30 8 ** 6,0

It was working correctly unitl this week, where I had a skipped execution for 13.01. No execution in the log, no error. Nothing. On the 12th there was a successful execution and on 14th the execution failed because of unability to connect to a MySQL database. On the 15th the execution was successful. However I do not seem to find any info or reason why the execution on the 13th was not triggered.

What is the error message (if any)?

No error messages for 13.01

I think the issue might be due to the way n8n handles scheduling and job execution. The custom cron schedule you’ve set seems fine, but it’s possible that there are other factors at play. Maybe try enabling “Allow Only One Entry” on your scheduled workflows to prevent duplicate executions?

The thing is I have a skipped execution and no track of what happened, not a duplicate one.

Of course, sorry about that. If there isn’t logging it simply didnt execute it as you said. But since jan 13th was a tuesday, your cron logic is correct, which means its likely an n8n issue.
