I have a problem i can't resolve. Here is the context : I have a blender file, i am using animation node addon. I have a animation node tree with a empty string list node. The elements in the list should be created programmatically with python.
When i call the create animation operator in a python console inside blender, the execution works:
Here is the create element operator :
bpy.ops.an.invoke_function_1(invokeWithData=False, confirm=False, callback="#('executeNodeCallback', (('NodeTree', 'summary_list'), 'newInputSocket'))", passEvent=False, data="None")
But when i call this operator from calling blender in the command line with a python script like so :
blender 'my blender file.blend' -P 'my python script.py'
Creation Operator is called in 'my python script.py'
I get this error in the command line terminal and the element is not created:
AttributeError: Calling operator "bpy.ops.an.invoke_function_1" error, could not be found
Any ideas of how to solve this error?
