Laksa::Crypto::Schnorr.sign signature size issue

[yivo]

Sometimes Laksa::Crypto::Schnorr.sign returns 126 bytes signature.

When trying to submit TX ZIL node returns: {"error":{"code":-8,"data":null,"message":"Invalid Signature size"},"id":1,"jsonrpc":"2.0"}

I noticed this issue on production account so I can't provide private key for testing but I will keep monitoring this in testing environment and if I catch this I will provide you a private key.

Here is how I use this gem:

      tx_parameters = Laksa::Account::TxParams.new.tap do |x|
        x.version        = 65537
        x.nonce          = nonce_of(issuer.fetch(:address)) + 1
        x.amount         = convert_to_base_unit(amount)
        x.gas_price      = 1000000000
        x.gas_limit      = 1
        x.sender_pub_key = issuer.fetch(:public_key)
        x.to_addr        = Laksa::Util::Bech32.from_bech32(recipient.fetch(:address))
      end

      tx = Laksa::Account::Transaction.new(tx_parameters, nil).tap do |t|
        t.signature = Laksa::Crypto::Schnorr.sign(Laksa::Util.encode_hex(t.bytes), issuer.fetch(:private_key), issuer.fetch(:public_key))
      end

      payload = tx.to_payload.tap do |p|
        p.merge! \
          amount:    p[:amount].to_s,
          gasPrice:  p[:gasPrice].to_s,
          gasLimit:  p[:gasLimit].to_s,
          signature: p[:signature].to_s
      end

Then I submit payload to ZIL by using CreateTransaction JSON-RPC call.
