AttributeError: 'NoneType'

[shapley]

Hi,

Been using the gisquick plugin and all has worked well but when I created a new QGIS project recently when I clicked on the 'gisquick plugin' then moving from 'Base layer' > 'next' the following error appears:-

An error has occurred while executing Python code:

AttributeError: 'NoneType' object has no attribute 'mapUnitsToLayoutUnits'
Traceback (most recent call last):
File "/home/paul/.var/app/org.qgis.qgis/data/QGIS/QGIS3/profiles/default/python/plugins/gisquick-qgis-plugin/project.py", line 291, in validate

units_conversion = map.mapUnitsToLayoutUnits()
AttributeError: 'NoneType' object has no attribute 'mapUnitsToLayoutUnits'

No idea why it won't now work on any project anymore. I'm using QGIS 3.12.3 on Ubuntu 20.04 LTS 64 bit.

Many thanks,

Hi,
from this traceback it looks like you have a print layout in your project, but without a map element. And right now, plugin doesn't expect such situation. If there is a valid use case for such layouts, then plugin could ignore them, but right now I'm not sure. I will let this issue opened for further discussion.

I can confirm that there is no missing map element. I've tried some variations such as removing all layers and adding them back in one-by-one, nothing is allowing me to move from this error even re-installed the plugin. I would like this to work. How do i go about getting some development time for it to work?

It doesn't look like problem with layers, but with print layouts in your project. If you open your project in QGIS, you can try to run this code in Python Console (Plugins menu) to get more info.

project = QgsProject.instance()
pm = project.layoutManager()
[[layout.name(), layout.referenceMap()] for layout in pm.layouts()]
