[error]: #0 unexpected error error_class=NameError error="uninitialized constant Aws::Lambda"

[acmmayur]

I was using this from long time with td-agent version 2.3.5-1.el2017.
Recently I updated td-agent version to 2.3.6-0.el2017.
After updating td-agent I am getting lots of errors for this module and its not working.
Can anyone help me to solve this issue ?
