[MapProxy] Display Original WMS Exception Messages

[Johannes Weskamm]

Hi,


There is no option for that i know of.

The closest thing is "on_error", but it returns custom colors and status
codes
(https://mapproxy.org/docs/nightly/sources.html?highlight=error#on-error)


I think the best bet is if you set the "Exceptions" Parameter on your
source URL to

"EXCEPTIONS=application/vnd.ogc.se_inimage"


That will render your exceptions as image and mapproxy may forward those
to you instead of raising an error.


Greetings,

Johannes
