[SR-Users] invalid char in json text

Playing around with ndb_mongodb

getting this error:

ERROR: ndb_mongodb [mongodb_client.c:262]: mongodbc_exec_cmd(): Failed to run command: lexical error: invalid char in json text

query is very simple: db.cdrs.insert({time:new Date(),src_user:"kelvin",term_ani:"14112",src_domain:"domain.com ",src_ip:"0",dst_ouser:"18188",dst_user:"18112",dst_domain:"domain.com"})

which is inside a pv mongodb_cmd("mgs1", "datab", "cdrs", "$var(MNG_MISSED)", "mgr1");

tried this: insert({time:new Date(),src_user:"kelvin",term_ani:"14112",src_domain:" domain.com",src_ip:"0",dst_ouser:"18188",dst_user:"18112",dst_domain:" domain.com"})

and other combinations, same error

any ideas? i guess we need some more examples on the documentation
