Unable to execute transaction using CeloProvider and Hardhat local node

[kosecki123]

Setup

yarn local

You should see standard output from the hardhat deployment and printed accounts:

Nothing to compile

Test 1

PK=<paste here the private key from listing above> CONTRACT=<paste here the address of deployed contract> node scripts/transfer_ethers_celo_provider.js

For me using PK and CONTACT above I would execute:

PK=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 CONTRACT=0x5FbDB2315678afecb367f032d93F642f64180aa3 node scripts/transfer_ethers_celo_provider.js

The output should have an error containing:

data: {
      message: 'Error: Invalid transaction. Only expecting 6 values (for unsigned tx) or 9 values (for signed tx).'
    }

Now, executing same transaction but using vanilla ether.providers.JsonRpcProvider as implemented in scripts/transfer_ethers.js ends without any issues.

PK=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 CONTRACT=0x5FbDB2315678afecb367f032d93F642f64180aa3 node scripts/transfer_ethers.js
