80306: Not Found Chat Service

This error occurs when the Proxy Service identified by {ProxyServiceSid} does not have a Chat Service associated with it. Configure the Service resource with ChatInstanceSid before you use Proxy to forward SMS or channel messages to Chat. A Proxy Service maps to one Chat Service instance.

• The Proxy Service was created or updated without a ChatInstanceSid. Twilio lists this property as optional on the Service resource, so workflows that rely on Chat can fail if you leave it unset.
• The ChatInstanceSid on the Service does not point to an existing Chat Service instance. Twilio expects this property to contain a valid Chat Service SID with the IS prefix.

• Update the Proxy Service and set ChatInstanceSid to the correct Chat Service SID for your application. Use a valid Chat Service SID that starts with IS.
• If the Chat Service was deleted or replaced, select the current Chat Service instance and update the Proxy Service so the one-to-one mapping is restored.
• If you use Proxy with channels, complete that setup against the same Proxy Service after the Chat Service association is configured.
