51101: Twilsock: Service instance not found

Twilsock could not find the Service instance identified in your request. This error usually means the Service SID is missing, malformed, or refers to a resource that does not exist in the target account or region.

• The request includes an invalid or mistyped Service SID.
• The Service instance was deleted and is no longer available.
• The request is being sent with credentials for a different Twilio account than the one that owns the Service instance.
• The client or server is configured to use the wrong environment, region, or Service identifier.
• The request is targeting a Twilio SDK product that requires a valid underlying Service resource, such as Chat, Sync, or Notify.

• Verify that the Service SID in your request matches an existing Service instance in your Twilio Console or application configuration.
• Check for typos, truncated values, or placeholder text in any parameter that identifies the Service.
• Confirm that you are using the correct Account SID, API Key, or Auth Token for the account that owns the Service instance.
• If the Service was deleted, create a new Service instance and update your application to use the new SID.
• Review your environment-specific configuration to make sure development, staging, and production credentials point to the correct Twilio resources.
• If you are using a Twilio client SDK, confirm that the access token and client configuration reference the intended Service and account.
