django.core.serializers.base.DeserializationError: Input string must be text, not bytes: (sentry.option:pk=5) field_value was 'False'

To fix it, I had to manually patch the JSON

{
  "model": "sentry.option",
  "pk": 5,
  "fields": {
    "key": "auth.allow-registration",
-    "value": false,
+    "value": "false",
    "last_updated": "2022-07-13T11:31:28.985Z"
  }
},


This issue happened for multiple objects that are of number or boolean type. Wrapping in quotes worked in all instances.
