Reproduction Example/SDK Setup

The base CDN bundle doesn't appear to be gzipped. However, more specific bundles are compressed as expected. Here's the resulting network payload.

https://browser.sentry-cdn.com/10.54.0/bundle.min.js - 88.6 kb
https://browser.sentry-cdn.com/10.54.0/bundle.replay.logs.metrics.min.js - 71 kb
https://browser.sentry-cdn.com/10.54.0/bundle.logs.metrics.min.js - 31.6 kb

I see the same across all major browsers. The uncompressed size looks fine. You'll see there's no "Content-Encoding" header on the base bundle response.

Hey @leigeber thanks for reporting! Currently looking into this.

It looks like we cached an uncompressed version of the bundle. Not sure yet how/why this happened but we purged the CDN cache and you should get the compressed version now. We're still looking into how to prevent this in the future.
