I am working on Bot framework technology, recently Microsoft announced the new version (V3) of bot. I was already developed bots using old version, now I am trying to upgrade my bots to newer version. For that everything working fine but after published my bot into azure, then by using the publish URL I am trying to test in bot framework channel emulator (3.0.0.54) it gives always "500, internal server error". But when I added skype channel to my bot then it will working fine.
Only the problem is when I am testing in bot framework channel emulator with Published URL of my bot application, then only I got the error as "Internal server error".
I think there may be problem with latest version bot framework channel emulator
