resource names need to be known on creation so this won’t work, you’ll need to use a known value

ok I changed it and I think I fixed that error but now I'm getting a stack error that tells me I'm missing a resource name argument where I've clearly defined one here's the new code

pub_rtas = []

for pub_subnet in pub_subnets:
    rta_name = pub_subnet.id
    newCall = pub_rtas.append(f"{rta_name}-public")

    ec2.RouteTableAssociation(
		resource_name = newCall,
	    subnet_id = pub_subnet.id,
	    gateway_id = igw.id,
	    route_table_id="HNO-route-table-public",
	)
