Hi Andreas,

Should be fixed by https://github.com/qgis/QGIS/pull/6874 . I'd
greatly value a test of that branch with the invalid project/model
combination to confirm that you get a helpful error message.

Hi, 

Issue solved - turned out that the layer in the project file was renamed
(by a colleague) and hence processing could not find the feature source.
All works fine now. Silly me! 

However, the processing error message was really misleading and had no
indication that it could not find the layer. Nyall is going to fix the
error message - thanks! 

Sorry about the noise - it is a classic "beginners mistake" ;-)

Sorry, not having worked with models, I don't know. Only thing I wonder is
whether it is a problem to have colons in a dictionary key
(native:orderbyexpression_1:Ausgabedatei).

Hi Tom, 

line 45 is 

processing.run("model:Anlagen-Export",parameters,feedback=None) 

The previous line is setting the parameters: 

parameters = {'vfewsanlagen':
QgsProcessingFeatureSourceDefinition('Anlage', True),
'native:orderbyexpression_1:Ausgabedatei' : 'C:/temp/ews_anlagen.xlsx' }


Thanks, 

Andreas
