Error: Unimplemented Type: 3

[stdmn]

I'm having problems with the new build of Tippecanoe. When trying to open Mapbox tiles, I'm getting the following error:

From blob:
skip: function(t) { var e = 7 & t; if (e === aa.Varint) for (; this.buf[this.pos++] > 127; ) ; else if (e === aa.Bytes) this.pos = this.readVarint() + this.pos; else if (e === aa.Fixed32) this.pos += 4; else { if (e !== aa.Fixed64) throw new Error("Unimplemented type: " + e); this.pos += 8; } },

...but only at higher zoom levels (13+). On Mapbox tiles created with older versions of Tippecanoe I'm not having any problems.

Self-contained version of JS Fiddle: https://jsfiddle.net/jncmz6qy/

I've tried with different settings on the Tippecanoe output. The current command line code is: tippecanoe -pk -pf -pt -ps --output-to-directory /path_to_directory/test /path_to_input/transit.geojson

This worked as of last week without any problems.

Every time I've seen Error: Unimplemented Type: 3 it's been because the vector tiles were gzipped but weren't unzipped before trying to parse them.

Sorry. You are correct. I have the tiles streaming from an Amazon S3 instance and for some reason S3 was only applying content-encoding metadata to some tiles. Closing issue.

The Mapbox Mobile SDK's do not report an error when .pbf are gzipped. Which makes debugging why a set of tile data doesn't render somewhat challenging.

On mobile, if you have .pbf that you are adding as{z}/{x}/{y}.pbf tiles be sure that the call to tippecanoe includes the --no-tile-compression format option (see Setting or disabling tile size limits)

For anyone debugging the validity of .pbf that was already processed for you and you want to know its compression state:

• port you Mobile style to a web page and check for error code: Error: Unimplemented Type: 3 in the browser. Example.
• As well, you can simply change the name to 0/0/0.pbf.gzip and see if the file gets larger. Then your tile at zoom 0 should be rendered.

How do you configure s3 metadata?

@stdmn could you elaborate on what kind of metadata that needs to be added?
