multiValueQueryStringParameters typing

[gregggilbert-ivadolabs]

The current way to type query parameters is by using the Annotated[str, Query()] types, but what happens when we need multiValueQueryStringParameters such as a list of strings?

By using param_1: Annotated[list[str], Query], Swagger UI will reflect it correctly, but when you "Try It Out", the resulting query would be decoupled in the URL (e.g., http://abc?param_1=value_1&param_1=value_2. This will raise an error because only one of the param_1 values will be retained by PowerTools' Query(), and an error will be raised saying that param_1 must be a list.

Any idea how multiValueQueryStringParameters can be handled and typed?

Hey @gregggilbert-ivadolabs! We don't support this right now, but we have an issue opened to implement it: #3622

We hope to implement it in future releases.

Thanks

Note that when splitting endpoints in multiple files using Routers, the router.current_event.multi_value_query_string_parameters is unavailable. Only available in the APIGatewayRestResolver.current_event. That should be considered in the open issue scope.
