53672: Video Room Transcriptions: Unsupported attribute(s) in TranscriptionsConfiguration

This error occurs when the TranscriptionsConfiguration object in a Room creation request includes one or more attributes that Twilio does not support for Video real-time transcriptions. If you enable TranscribeParticipantsOnConnect and do not provide TranscriptionsConfiguration, Twilio uses the default transcription settings.

• The TranscriptionsConfiguration object includes a key that is not supported for Video real-time transcriptions.
• A supported configuration property was misspelled or used with the wrong capitalization.
• The request used attributes outside the supported configuration set, such as properties other than transcriptionEngine, speechModel, languageCode, partialResults, profanityFilter, hints, or enableAutomaticPunctuation.

• Review the Debugger event for the specific attribute that caused the request to fail.
• Remove any unsupported keys from TranscriptionsConfiguration.
• Update property names to match the supported configuration fields exactly.
• If you do not need custom transcription settings, omit TranscriptionsConfiguration and create the Room with TranscribeParticipantsOnConnect=true so Twilio applies the default configuration.
