Checkpoint error when attempting to download a briefcase.

Any idea what this validation failure is about and/or how to solve it?

This error occurs when the iTwinId stored in the version of the iModel that you downloaded is different from the iTwinId that you passed to the downloadBriefcase call. How old is this iModel? Have you downloaded a briefcase for this iModel successfully recently?

The preferred way to fix this would be to try and clone the iModel to a new one. Since the 'iTwinId' property has had more than one name over the years its possible that this iModel does not even have the iTwinId property stored in it.

I believe the iModel we're attempting to download was created recently. When downloading the briefcase we're passing 'latest' for changeset/version since we are looking to pull the current version. Our service has downloaded a lot of iModels, this is the first one that has thrown the checkpoint error. It sounds like cloning the iModel would be a good place to start. We're running v4.8.1 packages if that makes a difference. Thanks.

Thanks for the extra information Rhaines. Did you have any luck with cloning the iModel?

In cloning the model I was able to download and read data from the briefcase. Thanks for the guidance.
