Michael A. Smith resolved AVRO-2411.
------------------------------------
Resolution: Won't Fix
Closing this ticket as I don't believe there is anything else that can
reasonably be done to improve this behavior unless Python upstream decides to
make `json.dumps` handle mapping objects more duckily.
> RecordSchema with logicalType field is not JSON serializable

> Key: AVRO-2411
> URL: https://issues.apache.org/jira/browse/AVRO-2411
> Project: Apache Avro
> Issue Type: Bug
> Components: python
> Affects Versions: 1.9.0
> Reporter: Jonathan
> Assignee: Michael A. Smith
> Priority: Major
>
> After updating to 1.9.0, RecordSchemas that contain a field with a
> logicalType mapping can no longer be passed into json.dumps() as it throws
> the following error:
> {code}Object of type mappingproxy is not JSON serializable{code}
> Example schema:
> {code}
> {
> "namespace": "Sherlock",
> "type": "record",
> "name": "Action",
> "fields": [
> {
> "name": "action_id",
> "type": "string",
> "doc": "Key for the Action"
> },
> {
> "name": "actionType_id",
> "type": "int",
> "doc": "Action Type key"
> },
> {
> "name": "timestamp",
> "type": {
> "type": "long",
> "logicalType": "timestamp-millis"
> },
> "doc": "Event time of validation request or modified_dt of save (UTC)"
> }
> ]
> }
> {code}
