SpringBoot #24877 still occurring when trying to read RequestMappingInfo directly

I have a method that is reading the mapping info in order to work with/validate api connectors

    protected String getHandlerMappingInfo(HttpServletRequest request){
        RequestMappingHandlerMapping mapping = this.ctx.getBean(RequestMappingHandlerMapping.class);
        RequestMappingInfo requestMappingInfo = mapping.getHandlerMethods().entrySet().stream().filter(){ entry ->
                    println(entry.getKey())
                    if(entry?.getKey() != "{ [/error]}"){
                        entry?.getKey()?.getMatchingCondition(request) != null
                    }
                }.findFirst().map(){ entry ->
                    entry.getKey()
                }.orElse(null);
        return requestMappingInfo.toString()
    }

This throws an identical error to #24877

I may be mistaken but I don't think this is completely fixed for all possible paths. (It also threw an error when path was "{ [/error]}" as well)

The path you see "{GET [//vehicle/vehiclesByManufacturer || //vehicle/vehiclesByManufacturer/**]}" is represented in the controller as @RequestMapping(value = ["/vehiclesByManufacturer**","/vehiclesByManufacturer/**"], method = RequestMethod.GET)

This allows for multiple URI's to be handled by one endpoint or for an endpoint to have an ALIAS and is covered in documentation.

I believe this may not be being considered for the pathing as it is throwing an error???

Where is that code written and called? If this is done outside of the Spring Boot or Spring Framework codebases (for example, a custom filter), this might be a duplicate of #28874.

No it is in springboot. Its in a filter: https://github.com/orubel/spring-boot-starter-beapi/blob/main/beapi-spring-boot-autoconfigure/src/main/groovy/io/beapi/api/filter/RequestInitializationFilter.groovy

Code is here: https://github.com/orubel/spring-boot-starter-beapi

I also added note up above; I believe this might be related to multiple @RequestMapping values

The code is a multimodule starter/autoconfig with demo project

That's definitely a duplicate of #28874. You custom filter is not initializing the request path. Note the comments in that linked issue saying that this is not an approach that the team supports. Thanks!
