Error: function () { [native code] } could not be cloned.

Hi @bahmutov this plugin is exactly what we need.

The first error I came across after following your steps was:
```
8:32:52 AM: Configuration error
8:32:52 AM: ────────────────────────────────────────────────────────────────
8:32:52 AM: ​
8:32:52 AM: Error message
8:32:52 AM: Plugins must be installed either in the Netlify App or in "package.json".
8:32:52 AM: Please run "npm install -D netlify-plugin-github-dispatch" or "yarn add -D netlify-plugin-github-dispatch".
```
So I did as the message suggests and ran `npm install -D netlify-plugin-github-dispatch`.

Then I can get further and the Netlify Deploy log returns this message from this plugin:

But the logs then show a second error, which I'm stuck on is:
```
8:35:32 AM: Plugin "netlify-plugin-github-dispatch" internal error

After this the Netlify Build Completes but my GH Actions workflow is not triggered.

Start by reproducing the Netlify Deploy with netlify-plugin-github-dispatch version 1.1.0 and inspect the onSuccess event path shown in the log, especially the plugin configuration from netlify.toml and package.json. Trace the function being sent through Netlify Build's child-process IPC, then verify that the deploy completes without the cloning error and triggers the configured GitHub Actions workflow.
