Hi @franchogarcia, I am sorry to hear you’re having trouble here. The node usually works fine for me, so I suspect the error might suggest an actual problem with a specific time zone.

Could you confirm which time zone you have selected in your workflow settings?

And does the problem also occur when picking a different one?

Hello @MutedJam!!
I am using the next time zone:

I have changed to the next:

But the error continues. Is it necessary to reload N8N or something similar?

Thanks so much for confirming @franchogarcia!

I tried this on my end but didn’t run into any trouble here, despite using your time zone :frowning:

So I suspect this might be related to your specific setup. Could you try installing the latest n8n desktop version (available at https://n8n.io/get-started/) and confirm if the problem persists?

If so, could you confirm if the n8n-desktop.env file inside the .n8n folder of your user’s home directory has any value set for GENERIC_TIMEZONE? Please do not share your entire file as it can include confidential data, just the line that starts with GENERIC_TIMEZONE= (if it exists).

Hi!
I have re-install again the n8n desktop and I have found the same error.
I have revised the n8n-desktop.env file and I have the next value for GENERIC_TIMEZONE:
GENERIC_TIMEZONE='Europe/Madrid'NODE_FUNCTION_ALLOW_EXTERNAL=lodash
For any reason I had in the same line both variables.
I have separated in two lines the both variables and I have put the time zone in the setup as:

And now it is running properly.
Thank you very much again for your support and help @MutedJam!! you are the best!!
