Lex V2 RecognizeText issue

Hi,

While it is difficult to exactly point the issue without enough details, you will typically face this error when trying to update the same session concurrently! For example two threads are trying to update the same session at the same time or two users trying to update the same session at the same time! So, to fix this please make sure there are no concurrent updates on the session.

I found the same issue. There were no concurrent access, but I was updating (creating) session using PutSession API call to prepare the lex bot, wait for this API to return and then immediately using RecognizeText API. Not sure if this is causing any conflict.
