Build Error—'There was an error parsing JSON for data.json' about starterkit-mustache-demo

[bmuenzenmeyer]

@prakashthangavelu until I can get a formal fix in - you can do the following.

1. open ./node_modules/patternlab-node/core/lib/pattern_assembler.js
2. find the following line, around 421:
   expandedLink = patternlab.data.link[linkMatches[i].split('.')[1]];
3. replace with
   expandedLink = encodeURI(patternlab.data.link[linkMatches[i].split('.')[1]]);

Can you run the .json in question through a site like jsonlint.com and see
if there is in fact malformed .json?

Yes I validated the data.json in jsonlint.com, but I didn't find any error.

[bmuenzenmeyer]

I've confirmed there is some bug with data.json link parsing in PL/Node.

The code is trying to convert

link.pages-about

into

/patterns/04-pages-05-about\04-pages-05-about.html

which, when stringified or put into json, is not likely valid json due to the single \,

@bmuenzenmeyer thank you. Its working.

[bmuenzenmeyer]

this was merged into PL Node Core and released.
