bug in v2.1.x? in revoke_security_group_ingress

[eniskonuk]

I'm getting the following exception when using 2.1.4 & 2.1.8 that works fine in 2.0.47. Any insight?

NoMethodError/undefined method `each' for #Aws::EC2::Types::UserIdGroupPair:0x007fc086830920

Thank you for reporting this issue.

There was a regression in serializing structure data types. The shared protocol tests exercised all of the code-paths of the param builder, but did not test with structure data types as input. This was was being tested for the other builder classes via their unit tests. I added a spec file for the EC2 param builder and added a test to cover this regression.

Sorry for the inconvenience. This fix should be released shortly.
