[Bug]: Fetch failed to localhost using Node Executor

### What happened?

While using Http Call Node with Node Executor, I get `TypeError: fetch failed`. Server does not get the requet.

```
Method: POST
URL: http://localhost:8000/evaluate
Body: {
"summary": "Hello bro!",
"file": "en-chat-1",
"type": "short",
"category": "personal"
}
```
While using Http Call Node with Browser Executor, the request is got by the server, but node responds with the expected error:` Error: Failed to make HTTP call. You may be running into CORS problems. Try using the Node executor in the top-right menu.`

### What was the expected functionality?

The request is sent.

### Describe your environment

MacOS, Node v20.12.2, Rivet 1.7.10.
