[YouTube-API] Get User Profile exception?

Hi,

I am a little unclear of the exception that is thrown if there is any
errors with retrieving a user's profile.

I am looping through an array and requested profile data for a few
youtube profiles. My problem is that the request is not always
successful. I always get inconsistant results and would like to catch
the exception and retry the request again until successful.

What youtube exceptions should I look out for when requesting user
profile data?

Thank you!
