Cannot change monday.com timeline start and end dates

[Yonas89]

Hey,

last week my http request node with this body worked well:

but this week i get an error that “JSON parameter needs to be valid JSON”
if i change start and end dates with static dates f.i “2025-01-31” the node works.

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:

Hi @Yonas89

Thanks for posting here and welcome to the community!

Can you check which actual values for the dates are in that failing JSON? i.e. what do your expressions evaluate to, when you get that error?

I’ve acctually managed to achieve my goals by using default monday.com change collumn node.
