I have a pretty similar problem like
I want to store static map tiles in .mvt format.
I use _headers files:
/tiles/* Content-Encoding: gzip Cache-Control: public, max-age=2592000, no-transform
I check in the browser that these headers are applied
But I see in the console.error ‘Unimplemented type: 7’ that signals about
[compression error](https://github.com/mapbox/mapbox-gl-js/issues/830#issuecomment-63874443). Something happened on the cloudflare side.
If I start local version with this headers or use other service — it works
What could it be?
