Caching worker returning 500s instead of wrangler binary

[nataliescottdavidson]

Several issues in wrangler have surfaced due to this. I haven't been able to reproduce the failure from the production worker https://workers.cloudflare.com/get-npm-wrangler-binary/1.10.3/x86_64-apple-darwin, though others have.

I cloned lasso and wrangler publish the caching worker to https://natdavidson.com/cache-wrangler-bin. Hitting https://natdavidson.com/cache-wrangler-bin/1.11.0/x86_64-apple-darwin in the browser produces could not find cache-wrangler-bin/1.11.0/x86_64-apple-darwin/index.html in your content namespace. curling the url returns
