PR opened here: https://github.com/globalvoices/NewsFrames-Code/pull/29

The solution is not great and should be removed as soon as this is fixed in Media Cloud.

Test normal expected URLs, just a bunch of MC entries. If you find unexpected error, please send time when you saw that to Scott so he can review logs.

MC search is not working. Following is the observation.

search Term and query URL from logged in user of MC is giving proper error - media cloud not responding MC query URLs (without login) like https://explorer.mediacloud.org/#/queries/demo/search?q=[{"q":"football%202018"}]&auto=true give unexpected error time 9:15pm-9:30pm IST

• the original issue works. that's fixed -- shruti, that URL is from the demo, and demo URLs aren't really the "real ones", so that's why it doesn't work. but we should be clearer somewhere about that, so i updated the .yml instruction in the develop branch -- ran across another issue created by the JSON, where the 'linefeed' character got added by accidentally hitting "return" in the Media Cloud textbox (https://explorer.mediacloud.org/#/queries/search?q=[{%22label%22:%22migration%22,%22q%22:%22migration%0A%22,%22color%22:%22%231f77b4%22,%22startDate%22:%222018-05-25%22,%22endDate%22:%222018-06-25%22,%22sources%22:[],%22collections%22:[9272347]}]). but we can't fix 'em all. so let's consider this closed.
