Multiple file upload Flux<FilePart> error on the swagger-ui

[oursy]

Given the following endpoint：

  @PostMapping(value = "/files", produces = {MediaType.APPLICATION_JSON_VALUE}, consumes = {MediaType.MULTIPART_FORM_DATA_VALUE})
    @Operation(summary = "files")
    public Flux<Void> handleFileUpload(
            @RequestPart("files") @Parameter(description = "files",
                    content = @Content(mediaType = MediaType.APPLICATION_OCTET_STREAM_VALUE))
                    Flux<FilePart> filePartFux) throws IOException {
        File tmp = File.createTempFile("tmp", "");
        return filePartFux.flatMap(filePart -> {
            Path path = Paths.get(tmp.toString() + filePart.filename());
            System.out.println(path);
            return filePart.transferTo(path);
        });
    }

Calling with swaggee-ui returns failure

I am using springdoc 1.3.9 & spring boot 2.3.0

@oursy,

The generated OpenAPI documentation looks correct.
The problem seems from the request on the swagger-ui.
It needs further investigations to be sure if the issue is on springdoc-openapi or on swagger-ui side.

@oursy,

I confirm the generated spec is correct, for your sample.

There is an open feature related to uploading files from the swagger-ui. Once fixed, we will add reference to the last version of the ui on springdoc-openapi.

There is an open feature request on the swagger-ui project. And here is the link for the right issue to follow:

• OAS 3: Support for uploading an array of files in multipart requests swagger-api/swagger-ui#4600

The fix will be available on v1.4.1.
