Enabling "Get images directly from WMS server" breaks printing #1223

Open shermp opened 5 years ago

shermp commented 5 years ago

What is the bug?

Enabling Get images directly from WMS server breaks printing.

I'm not sure if this is strictly a LWC issue, or a QGIS Server issue, or both. I'm leaning towards both.

Steps to reproduce the issue

  1. Add a WMS layer to QGIS project.
  2. Use Lizmap plugin to configure WMS layer and select Get images directly from WMS server
  3. Load map in LWC and attempt to print (Note, WMS layer displays successfully).
  4. Browser immediately shows the following error: This XML file does not appear to have any style information associated with it. The document tree is shown below.

Expected behavior

A PDF/png/etc should be generated and displayed/downloaded.

I see the following error :

Warning: error parsing post data as XML: at line 1, column 1: error occurred while parsing element. Assuming urlencoded query string sent in the post bod

It give me error when I try to print without WMS layer in my project but only with new created print layout.

rmarzocchi84 commented 5 years ago

Qgis server log using two different print layout. The first give me error the second works.

Can be a problem due to the duplication of a layer?

using the layout that give me error I have 5 layers and 5 styles while using the layout that works I have 5 layer and only 4 styles.. (no style for the duplicate layer)

But I do not understand why and how can I change this behaviour in QGIS?

rmarzocchi84 commented 4 years ago

The problem is still present. I check the QGIS Server configuration (xvfb intsall) but it do not works.

Here the qgis error log (level 1)

I have done some test with the followinf WMS. I read the problem can be related to WMTS? http://webapps.sit.puglia.it/arcgis/services/BaseMaps/Ortofoto2016/ImageServer/WMSServer
