It looks like you have a broken world file - can you find the world file
for that tiff and check it?

Hi,
Validation does not work with env function, but if you send de style
directly to geoserver without validation it works.
In fact, the same file with type="values" allows the previsualization of
the legend, but not with type="intervals".

Yeah,
I'm guessing that when the env function integration was added, legend
generation was not
updated to consider the possibility of expressions in the colormap entries.

Can anyone open a ticket with an example style? Seems like a good candidate
for the
monthly bug fix code sprint

Cheers
Andrea
