Converts JSON files into Python TypedDict source coe

json2typeddict's Issues

A json_node might be missing the properties key

Hi,

First, thanks a lot for the nice tool! This is the second time I'm making this fix, each at least six months away from each other :) Thus decided to propose it here:

diff --git a/json2typeddict.py b/json2typeddict.py
index 12fd054..f7579d8 100644
--- a/json2typeddict.py
+++ b/json2typeddict.py
@@ -78,7 +78,7 @@ def json2typeddict(schema):
         if node_type == 'object':
             py_node = ClassDescription(class_name)
             class_description_list.insert(0, py_node)
-            for property_name, property_node in json_node['properties'].items():
+            for property_name, property_node in json_node.get('properties', {}).items():
                 # I know underscores in class names are not PEP8 but it's just much easier to read generated code
                 walk(property_node, class_name + '_' + property_name, property_name, py_node)

This is probably happening when there are empty json objects with an automatically generated schema (i.e. with genson some.json | python3 json2typeddict).

Cheers,
T.
