I'm getting this error:

"Uncaught Template render error: Template render error: TypeError: Cannot use 'in' operator to search for 'as' in http://localhost:5000/user/search?_user=8b8c88412bd689883574d369beb20d24409…4b8c-a237-26bac31172db%2Cevan.moore24%40gmail.com&devSlug=test1&lang=en-US".  

I've tried (note that I changed the variable to camelcase):

    {% defer (apiParams('user.search', devSlug=devSlug), id='dev-search') %}
and
    {% defer (apiParams('user.search', {devSlug: devSlug}), id='dev-search') %}

Am I doing it wrong?
