Unable to add .ndpi WSI to QuPath project (DefaultImageServerBuilder error)

Error adding .ndpi WSI to QuPath project (DefaultImageServerBuilder)

Description

Using paquo 0.8.2 with QuPath 0.5.0, I get the following error when trying to add an .ndpi whole slide image to a project:

OSError: DefaultImageServerBuilder can't open {file path}

.svs files work fine — the issue seems specific to .ndpi.

Environment

• paquo: 0.8.2
• QuPath: 0.5.0

[ap--]

Does it load when you try to do this manually in QuPath 0.5.0 without paquo?
