Execution fails with no failed nodes

[Dave_Schafer]

Hi,
We’re having the same issue as reported here running on n8n cloud.

Execution failed without logs

Execution failed I am working on a workflow which sometimes fails, sometimes works fine. The problem is that when failing, it is impossible to dig because nothing show up when tryuing to inspect the workflow execution. Note that I can perfectly do it when it works fine. I know part of the loop was eecuted because i received some webhook. However not all my users received the webhook, and what is dramatic is I cannot tell to which of my users I must replay the workflow. Error message Can’t s…

I logged it as a bug but they can’t help. It seems as a platform if a failure is report some result should be available.

The workflow fails, the execution data is removed and no nodes are identified.

How can we move this forward.

Thanks
Dave

The error in the post you linked to happens when he n8n instance crashes in the middle of an execution. Is your n8n instance also crashing?
If not, are you using sub-workflows?

[Dave_Schafer]

We’re running on n8n cloud. I have no idea if the instance is crashing. I don’t know how we could see that.

We are using sub-workflows but even if the failure is in a sub workflow it normally bubbles up to the main workflow.
