Cannot generate geo_color

[gerritholl]

Describe the bug

An attempt to generate geo_color fails with a warning message

[WARNING: 2024-08-23 12:51:06 : trollflow2.plugins] Skipping geo_color: "No dataset matching 'DataQuery(name='geo_color')' found"

Expected behavior

I expect a geocolor image to be produced.

Actual results

No image is produced. Final output lines:
