Full Node Error

I try to run a Full node but I receive this error:

thread ‘main’ panicked at ‘Failed to load node config file! Given file path: “./fullnode2.yaml”. Error: BCS(“genesis”, Custom(“invalid value: integer 237, expected variant index 0 <= i < 1”))’, aptos-node/src/lib.rs:136:17

note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

How can I fix?
