Durable Objects RPC from pages to other worker

Hi! I have a worker using the durable object counter example https://developers.cloudflare.com/durable-objects/examples/build-a-counter/ I also have a pages in remix where I want to call the rpc method getCounterValue(), but on function execution I got the error in the image. Is that error something expected? Will be supported rpc between different wrangler sessions since for service binding is already supported?
