[MapProxy] ArcGIS compact cache - how to get it working

Dear List,

We are trying to figure out how the integration of an existing, local
arcgis compact caches works.

The instructions of https://mapproxy.org/docs/1.13.0/caches.html#compact
have been followed closely:

    sources: []
    grids: [utm]
      type: compact
      version: 2
      directory: D:\cache\_alllayers

The grid has been configured with the information from the corresponding
config files (srs, bbox, resolutions, tilesize).

Configuration saves without issues, but MapProxy only shows blank tiles
afterwards for that layer. There are no log messages / errors, and the
responses have status code 200, but the images are empty.

The cache has been created with ArcGIS Server 10.4. Is that version
supported at all?

Any ideas how to get things working, e.g. missing / undocumented parameters?

Thanks in advance,

J. Weskamm
