For a grayscale background map, I added a custom outputformat in MapServer. Using this image format with tilecloud I get this error:

Hello @yjacolin,
Where can we find the config file ?

sbrunner commented

The layer configurations should be:

...
mime_type: image/png
params:
    format: image/png; mode=8bit, grayscale
