We've been running a testnet and have executed a number of runtime upgrades. We've also upgraded the node across a variety of changes. New validators are trying to join the network and yet they cannot now run our genesis chainspec.
The network was probably launched around
Error: Service(Other("Error parsing spec file: unknown field phantom
, there are no fields at line 175 column 17"))
What's the proper way to debug this and how can we onboard new nodes to our network? It seems we're stuck.
