POST /api/v2/architect/flows returns 422 with WEM trigger in python-genesyscloud 2.14.3

POST /api/v2/architect/flows returns a 422 when pushing a WEM trigger via python-genesyscloud 2.14.3. Steps: deploy flow, trigger engagement, check gateway logs. Schema matches, but the gateway rejects the integrations.data.actions node. The serializer in genesyscloud/models/architect_flow.py line 412 drops trailing Z.

It’s doing jack all for prod. We’ve patched the encoder locally. The workaround holds the queue together. GitHub issue stays open.
