Each error is an object with the following shape:

```json Example error theme={null}
{
  "error_code": "seam_bridge_disconnected",
  "message": "Indicates that the Seam API cannot communicate with Seam Bridge, for example, if Seam Bridge executable has stopped or if the computer running the Seam Bridge executable is offline.\nThis error might also occur if Seam Bridge is connected to the wrong workspace.\nSee also Troubleshooting Your Access Control System.",
  "created_at": "2025-01-01T00:00:00.000Z"
}
```

<Accordion title="Error object properties">
  <ResponseField name="error_code" type="Enum (String)">
    Unique identifier of the type of error. Enables quick recognition and categorization of the issue.

    One of the error codes listed below.
  </ResponseField>

  <ResponseField name="message" type="String">
    Detailed description of the error. Provides insights into the issue and potentially how to rectify it.
  </ResponseField>

  <ResponseField name="created_at" type="String (ISO 8601)">
    Date and time at which Seam created the error.
  </ResponseField>

  <ResponseField name="is_bridge_error" type="Boolean">
    Indicates whether the error is related to the [Seam Bridge](https://docs.seam.co/capability-guides/seam-bridge).
  </ResponseField>
</Accordion>

### `account_disconnected`

Indicates that the login credentials are invalid. Reconnect the account using a [Connect Webview](https://docs.seam.co/core-concepts/connect-webviews) to restore access.

***

### `acs_system_disconnected`

Indicates that the [access control system](https://docs.seam.co/low-level-apis/access-systems) has been disconnected. See [Troubleshooting Your Access Control System](https://docs.seam.co/low-level-apis/access-systems/troubleshooting-your-access-control-system) to resolve the issue.

***

### `bridge_disconnected`

Indicates that the Seam API cannot communicate with [Seam Bridge](https://docs.seam.co/capability-guides/seam-bridge), for example, if Seam Bridge executable has stopped or if the computer running the Seam Bridge executable is offline.
See also [Troubleshooting Your Access Control System](https://docs.seam.co/low-level-apis/access-systems/troubleshooting-your-access-control-system#acs_system.errors.seam_bridge_disconnected).

***

### `provider_service_unavailable`

Indicates that the access control system provider's service is temporarily unavailable. Seam will automatically retry and reconnect when the service becomes available again.

***

### `salto_ks_certification_expired`

Indicates that the [access control system](https://docs.seam.co/low-level-apis/access-systems) has lost its Salto KS certification. Contact [support](mailto:support@seam.co) to regain access.

***

### `salto_ks_subscription_limit_exceeded`

Indicates that the maximum number of users allowed for the site has been reached. This means that new access codes cannot be created. Contact Salto support to increase the user limit.

***

### `seam_bridge_disconnected`

Indicates that the Seam API cannot communicate with [Seam Bridge](https://docs.seam.co/capability-guides/seam-bridge), for example, if Seam Bridge executable has stopped or if the computer running the Seam Bridge executable is offline.
This error might also occur if Seam Bridge is connected to the wrong [workspace](https://docs.seam.co/core-concepts/workspaces).
See also [Troubleshooting Your Access Control System](https://docs.seam.co/low-level-apis/access-systems/troubleshooting-your-access-control-system#acs_system.errors.seam_bridge_disconnected).

***

### `visionline_instance_unreachable`

Indicates that [Seam Bridge](https://docs.seam.co/capability-guides/seam-bridge) is functioning correctly and the Seam API can communicate with Seam Bridge, but the Seam API cannot connect to the on-premises [Visionline access control system](https://docs.seam.co/device-and-system-integration-guides/assa-abloy-visionline-access-control-system).
For example, the IP address of the on-premises access control system may be set incorrectly within the Seam [workspace](https://docs.seam.co/core-concepts/workspaces).
See also [Troubleshooting Your Access Control System](https://docs.seam.co/low-level-apis/access-systems/troubleshooting-your-access-control-system#acs_system.errors.visionline_instance_unreachable).
