+  [plone devs] (55bda5c9)
+
+
+3.0.2 (2023-03-14)
+------------------
+
+Bug fixes:
+
+
+- Type error is removed and none is returned.
+  In this modified version of the code, if no primary field adapter is found, the fieldname and field attributes are set to None.
+  The value property checks whether the field attribute is None, and returns None if it is, instead of raising an error.
