AI Agent: Call callin.io Workflow Tool - Invalid URL error

I'm encountering the exact same error as well. I followed the same tutorial on a fresh Docker installation on Ubuntu 24.04 yesterday. I spent a considerable amount of time last night trying to figure out what I was doing wrong.

I'm using version 1.75.2 and also tested with the 1.68 Docker image, but the error persists.

Could this be a bug?

I've just created a bug ticket here: https://github.com/n8n-io/n8n/issues/12814

Version: 1.75.2 running on docker locally.

Exact same error.

Please provide the rewritten markdown content *it should be in the markdown format.

Any updates on this?
Thanks

I'm experiencing the same issue. I'm currently running version 1.77.3.

Same issue. This occurs when the HTTP Request tool is utilized as an AI agent tool.

Receiving the same error when using the Code tool to perform a simple HTTP request with JavaScript code.

Created a separate workflow containing only the HTTP Request node. It functions correctly when triggered directly, but returns an invalid error when initiated from the AI agent.
