Can't activate simple webhook node - Please resolve outstanding issues before you activate it

Hey!

Ive used Zapier for a long time and just started working in n8n.

Ive created a simple webhook node but it refuses to listen for test run. I get the error “Please resolve outstanding issues before you activate it”. The AI assistent (whom I love) is unable to provide the solution.

Method is Post.

Path is /trigger-whatsapp

Authentication set to none.

Respond set to immediately.

Any idea? Thanks in advance fam!

Hello @Luc12, could you please share your workflow along with additional details about your n8n setup, such as the version and deployment type?
