unable to set timestamp field

[saumilsdk]

If item can't be mapped to timestamp field.
E.g. 'updatedAt' field is not getting mapped to 'timestamp'

item: {
        settingType: "settingType",
        timestamp: 'updatedAt',
        data: "data",
        metadata: 'metadata'
}

I dont see any problems with set timestamp field name into item.
I have tested and work, this question should be closed
