Invalid index file #6
Description
When running the first example I get the following error. Removing the map.zoomAll(); line allows it to render an image.
I'm not sure if it's the expected output since // expected output: https://github.com/mapnik/node-mapnik-sample-code/blob/master/outputs/map.png is a 404.
node ./render/app.js ./stylesheet.xml map.png
/Users/Steve/Play/mapnik/node-mapnik-sample-code/render/app.js:33
map.renderFileSync(image);

node -e "console.log(require('mapnik').version)"

This also happens in the tile examples. When the map.extent = bbox; line is removed it seems to work.

map.zoomAllis critical to rendering the image so removing it just resulted in a empty image. I found this which lead me to removing the.indexfile from my data. Now I am able to render the map successfully! Sounds like mapnik should handle the index file though?sethfitz commentedon Feb 4, 2016
@almccon and I recently ran into this too. It appears that somewhere in the mapnik-3.4 series the index file format has changed (we were reproducing it with 3.4.16).
We managed to solve it by using the
shapeindexalternative that now ships with node-mapnik:node_modules/.bin/mapnik-shapeindex.js/cc @springmeyer

I've just removed the index file from this repo to ensure that the same code works with all versions of node-mapnik. Sorry about being slow to help troubleshoot here but @mojodna had the right fix. More details at mapnik/node-mapnik#590
