The result of my workspace is several geojson files. For usability purposes, I want to include a fixed template .qgz file which is already on the server in the zip, so end users can immediately open it in QGis.
However, I can't find a way to get this to work with the Data Download service.
As a proof of concept, I created a minimal example that just loads a binary file, and writes it again. However, the AttributeFileWriter can't be selected as a Writer output for the Data Download service.
Is there another way to include arbitrary binary files with data download?
