Error listing objects - "listing too many items for gateway-side filtering"

While I don’t know for sure, I suspect there is no malice or ill intent, they just did not think of this, being busy implementing 4781 features nobody asked for.

Here is a curious discussion on duplicacy forum, in the thread dedicated to harsh critique of duplicacy itself, no less, a tangent about Kopia:

[kopia] suffers from featurecreep (support per file compression algorithm?!), while lacking basic necessities (support for filesystem snapshots), and the UI is written on Electron — just look at resource utilization of a simple two page UI.

Quite a few folks there expressed the same sentiment — great on paper, unusable in practice.
