Error when used as a next swc plugin

[stschroeder]

I am using swc-plugin-coverage-instrument (0.0.8) to instrumentalize my Next.js app (12.2.5). I am using the following next.config.js configuration:

const nextConfig = {
  reactStrictMode: true,
  swcMinify: true,
  experimental: {
    swcPlugins: [
        ['swc-plugin-coverage-instrument', {}]
    ]
  }
}

When I execute next build I get the following error:

$ RUST_BACKTRACE=1 npm run build

> swc-coverage-instrument-error@0.1.0 build
> next build

I think this is resolved with latest release + vercel/next.js#39499.
