OmniPresence WebDAV test returns "Server should not automatically assign a compressed MIME type"

I’m attempting to set up a WebDAV server for use with OmniPresence and I am getting this error message:

Server should not automatically assign a compressed MIME type, because it triggers automatic decompression when the file is retrieved.

I’ve been through my Apache/2.4.23 configuration files twice and I don’t see any incantations that would be automatically assigning a compressed MIME type. Does anyone have any suggestions about what I should be looking for? The Directory block for the WebDAV already contains RemoveEncoding .gz .Z to remove any encoding that would otherwise be done by the server.

We solved this problem by adding SetInputFilter DEFLATE to configurations for the “/webdav/“ path in our Apache config.

For reference, here are the docs on this concept:
