The Content-Encoding: gzip is correct, but the Content-Type: application/gzip is not if the intent is to serve a JavaScript script. it should be Content-Type: application/javascript.
Moving to needscontact.

The issue is still reproducible on my side.

Tested with:
Browser / Version: Firefox Nightly 69.0a1 (2019-06-10)
Operating System: Windows 10 Pro
The issue seems to be fixed.
For https://om.olacabs.com/om-app/vendor.bundle.js Content-Type is now application/javascript

Note: The layout also changed, now after navigating to the provided URL, I'm redirected to https://accounts.olacabs.com/?returnurl=https%3A%2F%2Fom.olacabs.com%2Fom-app%2Fhome and valid Indian phone is requested to create an account.
Tested with:

I'll close it as fixed.

It works now. Thanks.
