📄 Description

Description

Fixed TypeError crash in Teams webhook handler. json.loads(event_data.get("user", {})) passes a dict {} as default to json.loads() which expects a string. When the "user" key is absent from event_data, this crashes with TypeError: the JSON object must be str, bytes or bytearray, not dict.

Fixed

Teams webhook handler no longer crashes when "user" key is missing from event data

Additional Information

Tested by reviewing the code path and confirming the fix handles the missing key case
Self-reviewed the code changes
Rebased onto dev (replaces #22433)
