"Error: Scalar size does not match" Building sig-check

[dysbulic]

I have been reworking the build system a bit. I was unable to build initially b/c the 20th powers of tau aren't included in the distribution. I'm pretty sure the build process is unchanged. The commands that are running are:

• circom circuits/sig-check/circuit.circom --r1cs --wasm --sym
• npx snarkjs r1cs info "build/circuits/sig-check/circuit.r1cs"
• npx snarkjs zkey new "build/circuits/sig-check/circuit.r1cs" "build/ptaus/pot20_final.ptau" "build/keys/sig-check/circuit.zkey"
• npx snarkjs zkey contribute "build/keys/sig-check/circuit.zkey" "build/keys/sig-check/new_circuit.zkey" -e="1636395152546"
• npx snarkjs zkey export verificationkey "build/keys/sig-check/new_circuit.zkey" "build/keys/sig-check/verification_key.json"
• node "build/circuits/sig-check/circuit_js/generate_witness.js" "build/circuits/sig-check/circuit_js/circuit.wasm" "circuits/sig-check/input.json" "build/circuits/sig-check/witness.wtns"
• npx snarkjs groth16 prove "build/keys/sig-check/new_circuit.zkey" "build/circuits/sig-check/witness.wtns" "build/circuits/sig-check/proof.json" "build/circuits/sig-check/public.json"
• npx snarkjs groth16 verify "build/keys/sig-check/verification_key.json" "build/circuits/sig-check/public.json" "build/circuits/sig-check/proof.json"

The proof verification fails with Scalar size does not match. The same build steps work for the other two circuits.
