Hi, thank you for raising this issue, I'll try to took into it soon for a proper solution, in meanwhile the workaround is to declare desired schema with type mapping:

https://github.com/swaggest/rest/blob/v0.2.61/_examples/advanced-generic-openapi31/router.go#L84-L89

	// Create custom schema mapping for 3rd party type.
	uuidDef := jsonschema.Schema{}
	uuidDef.AddType(jsonschema.String)
	uuidDef.WithFormat("uuid")
	uuidDef.WithExamples("248df4b7-aa70-47b8-a036-33ac447e668d")
	jsr.AddTypeMapping(uuid.UUID{}, uuidDef)

thanks a lot, both for looking into it and the workaround!
