I am trying to get the data source of the layer in the Python action within the layer property. My code in the Python action is:

layer = iface.activeLayer()
QMessageBox.information(None, "parDir: ", layer.source())

When I run the action, the script returned the following error:

An error occurred during execution of following code:
layer = iface.activeLayer() 
QMessageBox.information(None, "parDir: ", layer.source())

If I run the same script in the Python console, it has no problem returning the name of the data source.

Does anybody know why the script failed if I run it as Python action?

  I've found the problem with the script. I need to add the following for the script to work: from qgis.utils import iface from PyQt5.QtWidgets import QMessageBox
