deepObject query parameter does not work

Q&A (please complete the following information)

• OS: Windows
• Browser: chrome
• Version: 131.0
• Method of installation: [e.g. npm, dist assets]
• Swagger-UI version: not sure. I am using

<dependency>
      <groupId>org.springdoc</groupId>
      <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
      <version>2.5.0</version>
      <scope>runtime</scope>
   </dependency>   

which seems to be using Swagger UI version 5.13.0. see this

• Swagger/OpenAPI version: [e.g. Swagger 2.0, OpenAPI 3.0] openapi: 3.0.1

Content & configuration

Example Swagger/OpenAPI definition:

parameters:        
        - name: metadata
          in: query
          required: false
          style: deepObject
          explode: true
          schema:
            type: object
            additionalProperties:
              type: string        

full config is omitted to show just the part in question

Describe the bug you're encountering

I do not see any field for metadata in the UI

To reproduce...

• declare a query parameter of type deepObject
• open Swagger UI

Expected behavior

I should be seeing a field to enter metadata information

Additional context or thoughts

https://github.com/swagger-api/swagger-ui/issues/4216

No source file or test is named. Start by loading the provided OpenAPI 3.0.1 parameter definition in Swagger UI and inspect how query parameters with style deepObject and explode true are rendered; compare the behavior with issue #4216. Done means the UI exposes a metadata input for this definition without regressing other query parameters.
