I've encountered this too. After some investigation, I've discovered its a bug <https://github.com/boto/boto/pull/2100> in Ansible/boto. The security token is not being passed through to boto and the AWS API call.
Looking at GitHub, it has been fixed, and the fix is in the v2.0 code, but it did not make it to the 1.9.x code. Go figure. I got around it by copying the v2 cloudformation module code into my module library. That works properly with assumed role credentials, and appears to be otherwise backward compatible. -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
