Spring：API生成八位字节流但JSON出错

实现一个API，它生成八位字节流，但如果ID无效，我想给出内容类型为JSON的错误响应

我的控制器是这样的

@RequestMapping(value = "/templates/{template_id}/preview", method = RequestMethod.GET,
            produces = {MediaType.APPLICATION_OCTET_STREAM_VALUE,MediaType.APPLICATION_JSON_UTF8_VALUE})
    @Versions(supported = {1})
    public ResponseEntity<InputStreamResource> getWatermarkTemplatePreview(@PathVariable("template_id") String templateId) throws IOException,
            MimeTypeException, DRMException {

        InputStream outputFileStream = drmService.getTemplatePreviewImage(templateId);

        // Adding mime type to file
        MimeType mimeType = MimeTypes.getDefaultMimeTypes().forName(MediaType.IMAGE_PNG_VALUE);

        return ResponseEntity.ok()
                .contentType(MediaType.valueOf("image/svg+xml"))
                .header("Content-Disposition", "attachment; filename=" + "preview" + ".svg")
                .body(new InputStreamResource(outputFileStream));
    }

如果我给这样的电子邮件ID http://localhost:8080/acpsserver/v1/drm/watermarks/templates/sdfrgtser/preview

我应该用JSON给erro

但是我得到 Internal Server Error http: 500

以下是我的堆栈跟踪
