You've created two certificates with precisely the same DNS name.

You can see in the verbose output that two certificates have been found as it lists two thumbprints. These values are then returned as an array which causes the error as the Signer parameter only expects a single certificate.

I suggest removing one or both certificates and trying again. I'll add an issue to the SIF backlog to cater for this scenario.
