Overview

The ‘multiValueQueryStringParameters` object from the API Gateway event keeps all values in an array, regardless of the actual size of the array and regardless of the “intent” of the query string parameter.

In order to normalise this behaviour, we treat the query strings

`key=value1&key=value2`

and

`key[]=value1&key[]=value2`

the same. Both are to be serialised to the query string

`key[]=value1&key[]=value2`

However, the query strings

`key=value`

and

`key[]=value`

are not to be treated the same.
