Quarkus + Resteasy + Google Cloud Functions: no query parameters bypass

Describe the bug I’m trying to implement a simple service using Google Cloud Functions and Quarkus. But if I’m trying to use @QueryParam annotation I’m getting nulls in any param. E.G.:

	@GET
	@Path("echo1")
	@Produces(MediaType.TEXT_PLAIN)
	public Response echo1(@QueryParam("test") String test) {
		return Response.status(Response.Status.OK)
				.encoding("UTF-8")
				.entity("test: " + test).build();
	}

Expected behavior

test: test string

Actual behavior

test: null

To Reproduce I’ve implemented a very small test service to reproduce the issue: https://github.com/HardNorth/quarkus-google-functions-test/blob/main/src/main/java/net/hardnorth/test/quarkus/QuarkusTestService.java

You need to deploy it into Google Cloud. Because it works locally.

Configuration Doesn’t matter at all

Additional context Based on what I see from code there is a missing part in QuarkusHttpFunction.java. E.G. for Amazon lambdas you have a whole loop which appends query parameters to path variable: https://github.com/quarkusio/quarkus/blob/master/extensions/amazon-lambda-rest/runtime/src/main/java/io/quarkus/amazon/lambda/http/LambdaHttpHandler.java#L154

But there is no such logic for Google Functions: https://github.com/quarkusio/quarkus/blob/master/extensions/google-cloud-functions-http/runtime/src/main/java/io/quarkus/gcp/functions/http/QuarkusHttpFunction.java#L94
