Upload dynamic multiple files in Nest JS

Question

I'm trying to upload files with dynamic keys, but nest.js needs to know key names.

I tried this one:

 @UseInterceptors(FilesInterceptor('files'))
    async uploadFile(@Query() minioDto: MinioDto, @UploadedFiles() files: Array<BufferedFile>) {
        const {bucket} = minioDto;
        return (await this.minioClientService.upload(files, bucket))?.name;
    }

Here files are static, but I want dynamic like:

@UseInterceptors(FilesInterceptor())
    async uploadFile(@Query() minioDto: MinioDto, @UploadedFiles() files: Array<BufferedFile>) {
        const {bucket} = minioDto;
        return (await this.minioClientService.upload(files, bucket))?.name;
    }

I even tried to get files from the request but I couldn't

You can upload multiple files dynamically using AnyFilesInterceptor provided by nest.js like below:

@Post('upload')
@UseInterceptors(AnyFilesInterceptor())
uploadFile(@UploadedFiles() files: Array<Express.Multer.File>) {
  console.log(files);
}
