Synthesis fails with "Could not find referrer npm package" when using a Helm chart with Deno

[aaronkyriesenbach]

Description of the bug:

Not sure if this is a cdk8s bug or a Deno bug but I'm starting here - please let me know if there's a better place to report this. I am running into errors synthesizing applications that use Helm charts (via both the Helm construct and chart-specific constructs generated with helm:... imports) along the lines of error: Could not find referrer npm package 'file:///home/aaron/.cache/deno/npm/registry.npmjs.org/cdk8s/2.69.52/lib/_loadurl.mjs' ([email protected]). This is only happening when building with Deno - the minimal reproducible example below synthesizes fine when using Node.

Reproduction Steps:

main.ts (this is the exact code used in the "Helm Support" example in the docs:

export class MyChart extends Chart {
  constructor(scope: Construct, id: string, props: ChartProps = {}) {
    super(scope, id, props);

    // define resources here
    new Helm(this, "redis", {
      chart: "bitnami/redis",
      values: {
        sentinel: {
          enabled: true,
        },
      },
    });
  }
}

Error Log:

$ deno run --allow-all main.ts

error: Could not find referrer npm package 'file:///home/aaron/.cache/deno/npm/registry.npmjs.org/cdk8s/2.69.52/lib/_loadurl.mjs' ([email protected]).

Environment:

• Framework Version: Latest as of writing, 2.69.52
• OS: Reproduced with the example above on macOS (M3) and Arch Linux

Other:

I've tried downgrading the version of CDK8s used, removing the Deno cache and re-running, etc. I honestly have no idea how to interpret this error so I'm not sure what's worth trying. I'm also happy to contribute to a fix for this if helpful, just would need pointers on where to get going.

Thank you for any ideas!
