Automatic connections FAILED on local setup

Hi team,

Today, I tried your new feature https://docs.metamask.io/snaps/how-to/allow-automatic-connections/ but immediately got some weird error that I couldn't debug myself. Please shed some light for my debugging. The error is thrown after I send RPC `wallet_requestSnaps` like below:

```js
return await provider.request({
method: 'wallet_requestSnaps',
params: {
[SNAP_ID]: snapVersion
? {
version: snapVersion,
}
: {},
} as any,
});
```
# The error:

# Environment:
- Chrome + Flask MetaMask
- Node v18.20.2

# Metamask dependencies `package.json`:
```json

Start by reproducing the wallet_requestSnaps call from the issue with the supplied Snap Manifest, Chrome Flask MetaMask setup, and Node v18.20.2. Compare the failure against the automatic-connections documentation and inspect the resulting error to determine whether the manifest or local origin is rejected. Done means the local setup succeeds or the required configuration is documented clearly.
