# My REST Client Formatter Returned 404 for Every Version

REST Client was on my VS Code extension list, so replacing it in Zed was the part of the migration most likely to have a gap. Two of the three pieces worked. The third no longer exists.

The working part is `httpyac`, a CLI that sends requests from `.http` files. Zed can run any command as a task, and it exposes the cursor line as `$ZED_ROW`. So the whole replacement is one task:

```json
{
  "label": "Run HTTP Request",
  "command": "httpyac send --line $ZED_ROW $ZED_FILE"
}
```

I bound it to `cmd-alt-r`, scoped to `Editor && extension == http` so it does nothing in other files. I tested it on a two-request file with the cursor on line 5. It ran only the second request and returned a 200. That is the behavior REST Client gave me, and it needed no editor plugin.

The part that failed was `kulala-fmt`, the formatter for `.http` files. I installed it and found that it downloads a helper called `kulala-core` from GitHub, and that download returned 404.

A single bad version was possible, so I tried more.

```plaintext
kulala-fmt 3.2.1   -> kulala-core download: 404
kulala-fmt 4.2.5   -> kulala-core download: 404
kulala-fmt 4.3.5   -> kulala-core download: 404
kulala-fmt 4.4.0   -> kulala-core download: 404
kulala-fmt 4.5.3   -> kulala-core download: 404
```

Five versions, one answer. The repo `github.com/mistweaverco/kulala-core` returns 404, so no version of the formatter can finish installing. The problem is upstream, and no config of mine could fix it.

I uninstalled it and removed the `format_on_save` entry I had added for it. I kept `kulala-ls` for completion and hover, because it answered a stdio `initialize` request. `.http` files go unformatted until upstream restores the repo.

One more thing I could not explain: `httpbin.org` times out from Node here with `ETIMEDOUT` while `curl` reaches it fine. I did not find the cause, so I test against a different host.

Checking more than one version was worth the minute. One 404 could have been my mistake. Five in a row is a fact.
