Issue #, if available:
None, but I can create one if necessary.
Description of changes:
We were seeing duplicated CORS headers in our app, which caused the browser to not allow the connection. The problem appears to be caused by code which puts the response headers in both
HeadersandMultiValueHeaders. According to the docs:So this may be a Lambda bug. But I can't see any reason to populate both maps and this patch appears to fix the duplicate headers.
