Tried switching from (old) RJSONIO to (newer) jsonlite but simpleTests.R balks on file upload.
@restonslacker Can you take a peek? It is curl/jsonlite interaction. Somehow the token gets lost.
it appears that RJSONIO and jsonlite didn't quite align at how to unnest a single object. RSJONIO returned a vector with a single character and jsonlite was returning a list with a single string. that solved the issue for me.
I looked at it, suspecting such a minor difference, but somewhat I was too dense. Or had too little coffee.
given that it took me 5 commits to make that change, i'd say you're not alone.
