SpringDelegatingLambdaContainerHandler seems does not work with query parameters

[astsiatsko]

Hello to everyone.
Spring boot 3.1.0
aws-serverless-java-container-springboot3:2.0.0-M2
Frontend service: ALB, API_GW, Functional URL
Deployment method: terraform or manual

Scenario

I want my java lambda microservice to process all types of events without additional expenses: ALB, API_GW, HTTP, Functional URL

Expected behavior

Behave the same way to all event types listed above

Actual behavior

When I use SpringDelegatingLambdaContainerHandler, I get error 400 every time I have query parameters for ALB event. if I use functional url event, I get internal server error.

Steps to reproduce

@RequestMapping(path = "/w6/test/{uuid}/refresh", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE) public ResponseEntity<TMaxmindResponse> refresh( @Parameter(description = "UUID of the order") @PathVariable("uuid") String uuid, @Parameter(description = "ID of the order(primary key)") @RequestParam("order_id") Long orderId, @Parameter(description = "tab") @RequestParam("tab") String tab )

I tried to wrap my head around it for 2 or 3 days, and found that when it tries to do

mvc.service(httpServletRequest, httpServletResponse);

it fails to error 400, no matter which parameters are. Also, if method parameters marked as optional, it returns exception and error 500, for instance, @RequestParam("order_id") Optional<Long> orderId,

After spending that much time, I decided that this is a bug and I really appreciate if this bug is resolved ASAP. Thanks

Hey guys, how may I include this fix in maven? Which version to use?

[deki]

It will be 2.0.0 but it's not released yet (likely beginning of next week).

[astsiatsko]

Thanks, will it be a new version like -M3?

[deki]

No it will be the stable release without a milestone.

[deki]

You can clone the repo and build from source if you want to validate the fix now.

[astsiatsko]

Yes but my question was - if I will wait for release on the next seek, will it be publicly available in maven central, etc?

[deki]

Yes, 2.0.0 will be also available on Maven Central.
