React-native: TypeError:expected dynamic type 'string', but had type 'object'

[Alleeeen]

1. react-native : 0.45.1
2. node : 6.3.1

3. npm : 3.10.3

4. Android

5. Development Operating System : macOS X EI Capitan
6. Build tools ： Android 25.0.0

After I upgrade the react version from 0.29.0 to 0.45.1, I got the following error:

TypeError:expected dynamic type 'string', but had type 'object'

It's been bother me for a few days, anyone who know how to solve this would be appricated.

Sounds like you might be calling the Alert native module with old/incorrect params? Just a guess.

Yes, I saw the code of Alert.js and figured out that this error is due to I call the Alert with a param of 'error' which is a object not a string anymore. The strange thing is this happened after I upgraded the react native version from 0.29.0 to 0.45.1.
