19028: Channel value can not be updated

You tried to update the channel value for an existing Verify configuration or resource that does not allow that field to change after creation. Create the resource with the correct channel from the start. If you need a different channel later, remove the existing resource and create a new one with the new channel value.

• The update request includes a channel value that is different from the value already stored on the resource.
• Your application reuses an update request payload that includes channel, even though the existing resource was already created with a different channel.
• Your integration attempts to switch a resource from one verification channel to another instead of creating a new resource with the required channel.

• Remove channel from the update request if you do not need to change it.
• Keep the existing channel value unchanged when you update other fields on the resource.
• If you need to use a different channel, delete the existing resource and create a new one with the correct channel value.
• Review your application logic to make sure create and update requests are handled separately and that immutable fields are not sent in update operations.
