Looking for advice on Predictive Routing skill mapping errors during Zendesk migration

Looking for advice on mapping Zendesk tags to Genesys Cloud skills for Predictive Routing.

The POST /api/v2/routing/queues call returns a 400 error when linking the queue. In Zendesk, we just used tags, but GC requires explicit skill assignments.

{"code":"bad.request","message":"Queue skill requirements do not match agent capabilities"}

How do others handle this mapping discrepancy in their migration scripts?
