ReferenceModelSpecificationToPropertyConverter Error log when missing 200 return code

Hi,

I have upgraded springfox from 2.9.2 to 3.0.0. I’m now using the Spring Boot starter for Springfox. I’ve got a non blocking error log when Swagger UI is loading;

2020-09-09 09:30:16.265 ERROR 42536 — [nio-9090-exec-6] nceModelSpecificationToPropertyConverter : Unable to find a model that matches key ModelKey{qualifiedModelName=ModelName {namespace='java.lang', name='Void'}
, viewDiscriminator=null, validationGroupDiscriminators=[], isResponse=true}

It happens when my PUT API just return a 204 HTTP code:

@ApiResponses(value = { 
        @ApiResponse(code = 204, message = "Resource updated") })

Temporary, I’ve patch my API by adding a code 200:

@ApiResponses(value = { 
        @ApiResponse(code = 200, message = "Fix springfox issue"),
        @ApiResponse(code = 204, message = "Resource updated") })

Could you please help me to qualify this issue?

I have the same problem, however the workaround does not help for me. Something like:

`
@ApiResponses(value = { @ApiResponse(code = 204, message = “Expected response to a valid request”), @ApiResponse(code = 500, message = “unexpected error”, response = Error.class) }) @RequestMapping(value = “/path/{id}”, produces = { “application/json” }, method = RequestMethod.DELETE)

ResponseEntity<Void> method( UUID sometId); ` results in ERROR: Unable to find a model that matches key ModelKey{qualifiedModelName=ModelName{namespace=‘java.lang’, name=‘Void’}, viewDiscriminator=null, validationGroupDiscriminators=[], isResponse=true}
