# We avoid including the "spot-instances-request" tag_specifications block when on_demand_failover_for_errors is defined,
# because when using on-demand fallback, the spot instance request resource is not created and thus the tags would not apply.
# Additionally, tagging spot requests via the CreateFleetCommand in the Lambda function does not work as expected,
# so we rely on Terraform to manage these tags only when spot is exclusively used without on-demand failover.
