60364: Challenge SID invalid or not provided

Twilio returns this error when your Verify request does not include a valid Challenge SID. Challenge resources are used by Verify Push and Verify TOTP, and the Challenge sid must be a SID<YC> value that starts with YC and contains 34 characters.

• The request did not include the Challenge sid.
• The value provided for the Challenge sid does not match the required format ^YC[0-9a-fA-F]{32}$.
• The request used the SID for a different resource, such as a Service, Entity, or Factor, instead of the Challenge sid.
• The Challenge sid was truncated, altered, or stored incorrectly before the request was sent.

• Send the Challenge sid returned by the Challenge resource in the sid field.
• Validate the SID before sending the request. Use a 34-character value with the YC prefix.
• Confirm you are passing the Challenge SID in the correct path parameter for endpoints such as /Services/{ServiceSid}/Entities/{Identity}/Challenges/{Sid}.
• Verify that the Challenge SID belongs to the same Verify Service and Identity you are using for the request.
• If you approve challenges from your backend or client application, validate that you are sending the expected challenge SID for that action.
