Http request error - evolution api

[codeNest]

I am trying to send a request through an HTTP Request node in n8n to interact with Evolution API. However, the node fails with a 404 error saying the requested resource could not be found.

The API should return a JSON response, but instead, I get an HTML error page with:

Cannot POST /instance/372afb3f-f1c0-4bae-b211-3103d1797b19/message/sendText

What is the error message?

The resource you are requesting could not be found
httpCode: 404
Cannot POST /instance/372afb3f-f1c0-4bae-b211-3103d1797b19/message/sendText

Please share your workflow

  }
}

Hi there, looking at the error, i think the problem lies on how you setup the evolution API and making it publicly accessible

Like, the address might be wrong

So the error is saying tht it cant find any process on that endpoint, so what you can do is maybe try to test it with like a postman as well and see if tht works or not

and to make it publicly available, try using something like cloudflare tunnel, ngrok, or any of tht similar tunneling services
