Updating to latest version renders Cron/Schedule trigger unoperational

[kristus]

Describe the problem/error/question

After updating to latest version (v1.59.4) all cron triggers / schedule triggers are forced deactivated. Please note that i update around bi-weekly and the cron task worked for past few months for me since i started using n8n. My server setup did not change. Only change was updating to latest version.

What is the error message (if any)?

On activation i get

There was a problem activating the workflow: "Invalid cron expression"

for Custom(cron)
and

Workflow could not be activated:
There was a problem activating the workflow: "ERROR: You specified an invalid date."

for selection via the dialog Trigger Rules -> everyday etc.

Please share your workflow

Share the output returned by the last node

no output, can’t not run

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

I’ve seen a few reports of this, but so far not able to reproduce this. So far all I can tell is that this has something to do with timezone.

What’s your instance timezone set to?

[kristus]

in docker-compose.yml i have
- GENERIC_TIMEZONE="Europe/Berlin"
and in the workflow it does not matter what i set for timezone, it still wont allow me to activate the workflows…

@kristus

• GENERIC_TIMEZONE=“Europe/Berlin”

Can you please try removing the quotes?

- GENERIC_TIMEZONE=Europe/Berlin

Thank you, that did it.
Did i miss these changes in the changelog?
I noticed also - N8N_LOG_LEVEL changed from verbose not being valid

n8n-1  | message: logs.level: must be one of the possible values: ["silent","error","warn","info","debug"]: value was "verbose"
