jsonparseexception: unexpected character (':' (code 58)): expecting either valid name character (for unquoted name) or double-quote (for quoted) start field name

my mapping structure 

{   "patientinfo": {     "properties": {       "address": {         "type": "nested",         "properties": {           "patient_current_address": {             "type": "string"           },           "patient_old_address": {             "type": "string"           },           "patient_origin_address": {             "type": "string"           }         }       }     }   } }

the code build bulk request looks this:

bulkrequestbuilder bulkrequest = client.preparebulk();  xcontentbuilder xb =  xcontentfactory.jsonbuilder().startobject();         xb.startobject();         xb.field("globalid","196ad302157add3ad63cd1154e968dfa");         xb.field("date_of_birth", new date());         xb.field("last_name","trying out rehman");         xb.field("id", "7");         xb.field("first_name", "anees");         xb.startarray("address");             xb.startobject();             xb.field("patient_origin_address","origin");             xb.field("patient_current_address","current");             xb.field("patient_old_address", "old");             xb.endobject();         xb.endarray();         xb.endobject();         bulkrequest         .add(client                 .prepareindex(index_name, index_type, "1")                 .setsource(xb));

my question how can deal date field inside :

querybuilder qbquery= fuzzylikethisquery("first_name","last_name","date_of_birth")              .liketext("anis")              .liketext("shahver")             .liketext("1985-05-15")

more_like_this doesn't support binary/numeric fields: [date_of_birth]]

-
here's current code creating index jsonb. index("mytable_data_idx_id_key", mytable.data['id'].astext, postgresql_using='gin') but got error. sqlalchemy.exc.programmingerror: (psycopg2.programmingerror) data type text has no default operator class access method "gin" hint: must specify operator class index or define default operator class data type.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
