lizmap-web-client: Edit layer : can't access to the edit form (loading progress bar)

What is the bug?

I try to edit a layer stored in PostGis. But when I select the layer in the Edition menu nothing happens but a loading progress bar. The form seems to be ok in Qgis and the cfg configuration file has no error.

Steps to reproduce the issue

1. Go to Lizmap Web Client
2. Click on ‘Edition’
3. Select layer to edit
4. See error

Expected behavior

Screenshots and logs

In Google Chrome Inspector I have the following error :

Failed to load resource: the server responded with a status of 500 (Internal Jelix Error)
http://IP/websig/lizmap/www/index.php/lizmap/edition/modifyFeature?repository=demo&project=Test_Projet_QGIS_218&layerId=epci_1720200107114840283&featureId=13

In Lizmap web client logs I have:

Environment

• Lizmap version: use of image ‘jancelin/docker-lizmap:3.2.1’
• QGIS Server version: use of image ‘jancelin/qgis-server:2.18LTR’
• QGIS Project version: tested with both 3.4 and 2.18
• OS (Windows, Linux, MacOS, Android…): Ubuntu Server 18
• Browser (Firefox, Chrome…): Chrome
• Lizmap admin information (users, logs…) stored into Sqlite (default)? PostgreSQL? MySQL? no changes, admin infos are stored in SQlite.

Any help would be very appreciated, thanks !
