17502: Invalid sourceId — not a valid Recording SID

Twilio can't create a new transcription because the supplied sourceId isn't a valid Recording SID.

• The value doesn't begin with the RE prefix.
• The value isn't 34 characters long (the prefix plus 32 hexadecimal characters).
• The value contains characters outside the hexadecimal range (0–9, a–f).

• Supply a valid Recording SID that starts with RE followed by 32 hexadecimal characters.
• Verify that you copied the SID correctly from the recording resource in Console or the REST API response.
