Handle requestContext function in policy expansion

Open BernieWhite opened this issue 3 years ago • 0 comments

Description of the issue

Similar to #1323 we need to handle requestContext() using expansion of policies.

Error output

An error occurred evaluating expression '[requestContext().apiVersion]' line 28634. The function "requestContext" was not found.
