Description

Describe your issue in detail. Include screenshots if needed. If this is a regression, let us know.
I found there is a very big number (20771272033) in bundle, it works well when I pass bundle to my mobile and load it normally. But when I want to debug on my device, my app crashed.

Exception is :

I have found the number 20771272033 in my bundle:

also, I found it parse this number as integer:

Is this a bug or I generated my bundle in a wrong way?
