Parsing error while using yelp scope

[Penk Chen]

I have com.canonical.scopes.yelp 1.5 installed on rc-proposed channel, and it doesn't display any data whether using fake location or not, in scope-registry.log I see following error:

2016/05/11 15:22:51 Starting yelp scope

I just installed yelp 1.5 and did not see this on:

channel: ubuntu-touch/rc-proposed/bq-aquaris-pd.en
last update: 2016-05-10 15:44:25
version version: 45

I think the issue is that the http request is assumed to return json. If yelp returns HTML then the decoding into a struct fails and that error is not handled:

Since this is intermitant and has existed all along, I'll set to High

I met this issue while implementing the new Yelp API V3, and I reported error to Yelp team.

This error is solved by Yelp. I tested thousands of times while testing lp:1626381, it never happen.
