My basic LLM Chain is not working. I’m trying to set up a chain with Gemini API to process images and return structured analysis.

error message (if any)?

Request failed with status code 503

workflow:

output returned by the last node- its keep cycle no reaching the chat model itself

Information on your n8n setup

n8n version:1.77.0
n8n EXECUTIONS_PROCESS setting default
Running n8n via render used via normal bowser also not working

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 @ASHWIN_HG,

Welcome to the community :tada:

Not sure if I understand what you mean here, could you elaborate? But in general a 503 error usually means the server is temporarily unavailable or overloaded. It could be a server overload if too many requests are coming in at once for example. Could you check that the services you’re connecting to are all available and that you’re not hitting the API’s request limits?
