Store API Error "Keyword must be 1152922700007114623 characters or fewer."

Question

Hi,

I am using Store API to publish my app. When i issue commit in Store API, It returns me following error. Can anyone please help me to understand this error?
Keywords specified are definitely less then 40 characters as required. but error shows some vague number that does not make sense.

Can MSFT Store API Team throw some light.
