Does anyone know why I'm getting the following error on Mac, connecting to Pulumi Cloud?

policy pack <path-to-folder-containing-PulumiPolicy.yaml> failed to start: could not read plugin [/opt/homebrew/bin/pulumi-analyzer-policy] stdout: EOF

Maybe it's what we're trying to do that off, but we're trying to make a central policy pack with the following

index.ts

, which is going to published in an npm packages

import { Guard } from './guard';

import './policy-groups/<custom policy>';
... repeating more policies

export { Guard };

And then in the specific use-case we'll do the following (this is importing from local, but I suspect this shouldn't matter

import { Guard } from '.';

export default new Guard('policy-pack', { all: 'mandatory' });

And then applying it to the Pulumi stack.preview() method as follows

await stack.preview({
    onOutput: (message: string): void => {
      process.stdout.write(message);
    },
    diff: options.diff,
    policyPacks: [
      path.join(
        context.root,
        context.workspace.projects['pulumi-policy-pack'].root
      ),
    ],
    ...
})

I'm not sure if this way of importing/exporting a policy guard would actually work as we expect, but the error message is pretty much useless so really unable to properly troubleshoot it. We're largely taking inspiration from this repository: https://github.com/pulumi/pulumi-policy-aws/blob/master/src/index.ts
