error putting a long value

[evaimitico]

Is there any lenght limit for the value while doing a put on db?

i'm doing:

var flatfile = require('flat-file-db');
var db = flatfile.sync('mydb');
var key = 'key1'
var value = '';
db.put(key,value)

JsonObjectPassedAsParam is a parameter. the snippet of code is working, but when i try to write particularly json objects, it give me the following error:
Cannot read property 'length' of undefined

As attachment, one of large jsonObject impossibile to write.
