Workflow get error but without displaying it

Describe the problem/error/question

Hello everyone, I am running a workflow that get contact from X and create it in Y.
I am running this loop using the {{$runIndex}}

What is the error message (if any)?

That’s my problem, the workflow at some point get error, and once I enter in the execution view I can see that the workflow did only one run (it’s not true, cause in the other client the workflow created X times the contacts),


The workflow show only success node, and If i click on any nodes the message is:

I’ve tried to re-execute the workflow from the node error, but not worked.

Please share your workflow

Hi @Gabriele_Bracciali :wave:

Are you receiving any other errors that might pinpoint exactly where the workflow is failing and why? :thinking: Are you running n8n via cloud or self-hosting? If you’re self-hosting, do you have any server logs from around when this execution fails?

hi @EmeraldHerald , no any other errors, that’s the point, the workflow doesn’t show where it fail, like the screenshot above show everything is green.
I am running n8n via self-hosted, at the moment I can’t see the logs

Hi @Gabriele_Bracciali - we’d probably really need to have server logs to know what’s going on here, I’m afraid - in this case, we’re not sure if n8n has just crashed, or if there’s issues in the workflow :see_no_evil:

You could try to view the execution data through the browser by visiting https://n8n.instance.url/rest/executions/123 - where you’d replace those details with what’s relevant for your own instance. You’re also on quite an old version of n8n, so you might want to upgrade to the latest version to have all possible bugfixes, etc.
