Testing [MapProxy] EPSG 23031

[Vidal, Antoni]

Hello again,

I'm trying to use MapProxy with a WMS service using EPSG 23031, but I get a white image with the exception message:

response is not an image: (<?xml version="1.0" encoding="utf-8" standalone="no"?><ServiceExceptionError version="1.1.1"> <ServiceException>(16389) ISItem::extract: decode (ul=65961.566598,5021619...

My service.yaml contains this layer:

    # #########################
    # # Layer from TMS Source
    # #########################
    icc:
        md:
            title: ICC WMS - www.icc.cat
        param:
            # cache tiles in format:
            # format: image/png

            # cache projected and geographical SRS
            srs: ['EPSG:4326', 'EPSG:900913', 'EPSG:23031']

            # store another level between each regular level
            res: 'sqrt2'

            # request all data in this format:
            # request_format: image/png

            # use a tile size of:
            tile_size: [256, 256]
        sources:
        - type: cache_wms
          req:
            url: http://shagrat.icc.es/lizardtech/iserv/ows?
            layers: mtc50m
            # styles:
            # transparent: False

My proxy.yaml starts with:

# #########################
# # MapProxy configuration
# #########################

# # which servers should be started?
server: ['wms', 'tms', 'kml']

# # WMS server options
wms:
     # supported image formats
     image_formats: ['image/jpeg', 'image/png', 'image/gif', 'image/GeoTIFF', 'image/tiff']
     # supported SRS
     srs: ['EPSG:4326', 'EPSG:4258', 'CRS:84', 'EPSG:900913',
           'EPSG:31466', 'EPSG:31467', 'EPSG:31468',
           'EPSG:25831', 'EPSG:25832', 'EPSG:25833', 'EPSG:23031']


# # when set to True return tracebacks on error # # do not enable this in production!
debug_mode: True


Request to original WMS server:
http://shagrat.icc.es/lizardtech/iserv/ows?REQUEST=GetMap&VERSION=1.1.0&SRS=EPSG:23031&Service=WMS&BBOX=290000,4538500,302000,4543500&WIDTH=1200&HEIGHT=500&LAYERS=mtc50m&%20%20STYLES=&FORMAT=JPEG&BGCOLOR=0xFFFFFF&TRANSPARENT=TRUE&EXCEPTION=INIMAGE 

Request to MapProxy that generates the error:
http://localhost:8080/service?LAYERS=icc&FORMAT=image%2Fjpeg&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG:23031&BBOX=290000,4538500,302000,4543500&WIDTH=1200&HEIGHT=500 

Any idea why it doesn't work?

Thank's a lot.
