To export ‘multiple’ fixtures, this syntax in hooks.py works for me:
fixtures = [{
"doctype": "DocType",
"filters": { "custom" : ["=", "1"] }
},
"Custom Field",
"Custom Script",
"Property Setter",
"Print Format"
]
The above you will find here Error installing custom app having ERPNext custom Doctype in fixtures
