Image directive scale parameter unsupported. Missing error message.

[dadada]

Tried the longer example for an image directive from https://docutils.sourceforge.io/docs/ref/rst/directives.html#images

.. image:: picture.jpeg
   :height: 100px
   :width: 200 px
   :scale: 50 %
   :alt: alternate text
   :align: right

Then run flamingo server -s settings.py --debug.

This shows

And the console output is

$ flamingo server -s settings.py --debug
ERROR:flamingo:content/index.rst:45: Error in "image" directive:
starting server on http://localhost:8080/

This is missing some useful debug output, even though the --debug flag has been passed.

Same thing with flamingo build -s settings.py --debug

This looks like the error message is truncated to a single line when running without --debug or in as a server. Also, the useful part of the error is printed as a debug message.
