   Cross posting the current work-around as a loader, using -r /opt/nodejs/.pnp.cjs --loader /var/task/hackey-hack.mjs:

   /*
   - Our .pnp.loader.mjs uses the parentURL, to try to pickup .pnp.cjs which fails.
   - It does not seem to use any of our env variables to set the yarn cache either.
   - Pretend we are in /opt/nodejs/ so it picks up .pnp.cjs and the .yarn folder.
   */
   const esmpnp = await import("/opt/nodejs/.pnp.loader.mjs");
   
   export async function resolve(specifier, context, nextResolve) {
     const parentURL = context.parentURL?.replace("file:///var/task/", "file:///opt/nodejs/");
     const contexts = { ...context, parentURL };
     const resolve = await esmpnp.resolve(specifier, specifier.startsWith("./") ? context : contexts, nextResolve);
     return resolve;
   }
   
   export async function load(urlString, context, nextLoad) {
     const load = await esmpnp.load(urlString, context, nextLoad);
     if(urlString === "file:///var/runtime/index.mjs") {
       const prepend = 'const { default: pnp } = await import("/opt/nodejs/.pnp.cjs"); pnp.setup(); const esmpnp = await import("/opt/nodejs/.pnp.loader.mjs");';   
       load.source = prepend + "\n" + load.source;
     }
     return load;
   }
