Hi,
PFA minor patch to handle "char" type while creating columns in Column node.
Issue: simplejson parse '"char"' as valid json, hence when we perform simplejson.loads(request.args) operation '"char"' gets converted to 'char'
I had to handle it manually as of now, I did not find any other workaround to handle this issue, I went over several SO question most of them suggested manual handling.
This behavior is only in Column node, table & type nodes are not affectted by .loads() method as we send data as column collection.
RM#2152
Snippet of issue:
import simplejson as json
print(json.loads('"char"'))
