[Qgis-user] NameError: name 'iface' is not defined when importing script to processing toolbox

[Cliff Patterson]

When trying to add a script to the processing toolbox, I get the following
error (below) even though iface is imported with "from qgis.utils import
iface" in the script. The problem existed with QGIS 3.6 so I upgraded to
3.10 on Windows 10, but it persists, I am using the standalone installer.
Any ideas how I can fix this error?


Thanks!

Cliff
