Generic Error Page

If your callback URL is valid, when an authorization error occurs, the Authorization Server returns the appropriate error and state parameters to your callback URL. In cases where your callback URL is invalid, your application will display the default generic Auth0 error page. (Alternatively, you may configure custom error pages.)

To learn how to find the default page name for the generic error page, see Use Version Control to Manage Your Universal Login Pages.

The generic error page will display the following information if you have configured the associated fields in your Tenant Settings.

Field	Description
Friendly Name	Name of your company
Logo URL	URL of your company logo
Support Email	Email address of your company's support team
Support URL	URL of your company's support page

If you choose to use the generic error page, the Authorization Server will return parameters appended to the URL as a query string.

Parameter	Description
`client_id`	Identifier for the Auth0 application
`connection`	Connection used at the time of error
`lang`	Language set for use at the time of error
`error`	Status code corresponding to the error
`error_description`	Description of the error
`tracking_id`	Identifier used by Auth0 support to find errors in internal logs
`log_url`	Link to the error in your tenant logs

Parameters presented vary depending on the error type and are specific to the request. If, for example, the request which resulted in an error did not contain a client_id, no client ID will be returned by the error page.
