Lambda Proxy integration queryStringParameters special characters

Question

I'm in the midst of testing a new AWS SAM application, and I found a bug that i'm having trouble solving.

I have a route with a simple GET request

/myRoute

and this route support query params such as "mail"

so the full url looks something like this

/[email protected]

aws is creating the proper event for me my problem lies when I have special characters inside my string params for example [email protected] than what I'll actually get after aws-sam interpret the call is "mymail [email protected]" with a space instead of the special character +.

Any ideas?

This isn't an issue with SAM, Lambda, or API Gateway. The + symbol indicates a space (see this answer on that subject). You should URL encode your query string parameters, and decode them in your Lambda. The + symbol is %2B.
