Summary
Changes
This PR updates the logic of the converter for API Gateway REST to account for query string values that are present multiple times.
Before this PR the values were repeated when passed to the route handler because they appeared both in the
queryStringandmultiValueQueryStringlists. Now the values are filtered and only one appears.In the process, I also had to refactor the
proxyEventV1ToWebRequestfunction beyond this specific change to reduce its cognitive complexity and please SonarQube.Issue number: closes #4750
