How do I know what exception to catch?

Question

I am dealing with an exception with this message. It is not a StandardError.

I caught it by catching the Exception class, but a post tells it is a bad solution. How do I determine what exception to catch?

Look at the source code for your API you are using and catch what exception that method is using. — Eli Sadoff, Jul 07 '16 at 15:03
If you can reproduce an error you can debug certain exception type. — Aleksey, Jul 07 '16 at 15:06
Looks like it falls down to timeout so likely to be `Timeout::Error` based on the [docs](http://ruby-doc.org/stdlib-2.1.1/libdoc/timeout/rdoc/Timeout.html) — j-dexx, Jul 07 '16 at 15:09

Temporary add to your code

rescue Exception => e
   puts e.class
end

And you will know what exception to catch

thanks, nice tip ^^. One issue tho : I need to let the code run for more than 5 to 8 hours to be able to get it. I will try that and tell you when I get it
