51101: Twilsock: Service instance not found

Description

description page anchor

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.

Possible causes

possible-causes page anchor
  • 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.
