Generate PDF bug, Deephost extension

I’m try to use Generate PDF Extension of DEEPHOST (Generate PDF Extension – DeepHost Extension) but it’s not working

My blocks:

PDF isn’t created on name and path set in the blocks

The path’s PDF created: /Android/data/io.makeroid.companion/cache/generate-pdf/output.pdf

The creator (DEEPHOST) show this block but i don’t understand

As Deephost is not a member of this community, you have to contact him directly

you need to use Access Filer Permission extension along with this to save the File.
