Multipart don't working for ArrayObject files with Open Api 4.3.1 Version - spring-boot

Question

Description
Hi Everyone. I am working with open api generator and change for only use Reactor in my projects (Flux and Mono). My problem is when I generate Multipart form for object array files, the generator create #RequestPart with Mono and it's will be geerate with Flux because the object is an array.
I check the mustaches templates for form params and all it's ok.
This is part of my formParams.mustache
{{#reactive}}{{#isArray}}Flux{{/isArray}}{{^isArray}}Mono{{/isArray}}{{/reactive}}{{^reactive}}{{#isArray}}List<{{/isArray}}MultipartFile{{#isArray}}>{{/isArray}}{{/reactive}}
My question is: why the generator don't validate when "isArray" because always generate with Mono in my classes.
This is an example how to generate my ApiDelegate:
with single element (Ok): default Mono multipartSingle(Mono file, ServerWebExchange exchang

Answer 1

I can resolve it changing in forms.mustache to {#isArray} to {#isListContainer} and it's works fine without changing version of plugin
