Hi Morris,

Welcome to the community.

I’m noticing in the screen shot that you don’t have your webhook workflow activated.

If you look at the executions tab for your workflow, does it show the webhook being called?

work around solution found.

previous node pass json.text string to llm(prompt: define below) is not working properly (no any trigger)

we make a code node to changet the json.text string to json.chatInput and make the option to “take from … automatically” works now. t **he LLM node triggered by code node.**

DONT KNOW WHY!! but it works now.
