Hello,

I encounter a problem with a (docker-hosted) version of QGIS-server 2.18.18 
(built from Source).

When I perform a WMS request on server, I always get a InvalidCRS error :
<ServiceExceptionReport version="1.3.0"><ServiceException 
code="InvalidCRS">Could not create output 
CRS</ServiceException></ServiceExceptionReport>

The same request sent on a 3.1 version of qgis-server performs well!


http://myContainer/qgis?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=layer1&MAP=%2Fdata%2Ftest_2.18.qgs&CRS=EPSG%3A3857&STYLES=&WIDTH=2471&HEIGHT=1237&BBOX=-408661.0170981592%2C6217550.309401342%2C-361442.04287499154%2C6241188.460398533

(I also tried with version 1.1.1 and 'SRS').


When I perform getCapabilities, I saw thoses lines including an empty <CRS/> in 
the 2.18.18 response.
Since they are CRS-related, this might be a clue :

3.1
<Layer><Name>layer1</Name><Title>layer1</Title><CRS>CRS:84</CRS><CRS>EPSG:3857</CRS><CRS>EPSG:4326</CRS>

2.18.18
<Layer 
queryable="1"><Name>layer1</Name><Title>layer1</Title><CRS>CRS:84</CRS><CRS/><CRS>EPSG:4326</CRS><CRS>EPSG:3857</CRS>


The only other remarkable difference I noticed : it appeared that the 
QGIS_PROJECT_FILE in server 2.18.18 is not used (that's why I had to set it in 
the URL), when it is used in the 3.1 version.
There are other differences, but none that looked concerned with my problem ... 
according to me! I may be wrong indeed... thus you'll find both the response to 
getCapabilities enclosed!.


I have created a project from scratch, from a shapefile with a few dots, and 
still I have the problem..
The WMS capabilities are set, and the layer name as well as the BBOX and the 
file name are ok.

So if anyone has a tip here...

Thanks by Advance.
