Hi colleagues.

Screenshot_20230117_030649
If you see above attached picture, have a trouble to download file and received such kind of exception. Actually code is like this in the StandardDetailView<T>:

InputStream inputStream = new FileInputStream("excel-file-path");
FileRef fileRef = fileStorage.saveStream("name.xlsx", inputStream);
fileTransferService.downloadAndWriteResponse(fileRef, fileStorage.getStorageName(), false, RequestContext.getResponse());

Can you provide most suitable way to download any created file(example: from apache poe to insert values) programmatically.

Thanks in advance!

Hi!
Have you tried it Downloading and Displaying Files :: Jmix Documentation?
