[MapProxy] Problem using MapProxy as a TMS client for a WMS server

[John Taranu]

I'm trying to use MapProxy as a TMS client, producing tiles as a WMS
service.  That is, it reads tiles from another TMS service and combines them
into a larger WMS image.

 

Unfortunately I get the following error when making a WMS request:

<ServiceException>Could not get retrieve any sources:

tile size of cache and tile source do not match: (256, 256) != (1114,
679)</ServiceException>

 

The request looks like this:

http://mapproxy/service?LAYERS=ortho_2008&REQUEST=GetMap&FORMAT=image/jpeg&W
IDTH=1114&HEIGHT=679&BBOX=662764.77,4884158.7,663495.62,4884604&SRS=EPSG:269
17&VERSION=1.1.1&STYLES=&SERVICE=WMS

 

Here's the relevant portion of the mapproxy config file:
