Running truffle tests with a "send from" has the following error

eth_getLogs

  "fromBlock": "0xc"
}

Standard ERC20 unit test

  it.only("owner should allow alice to transfer 100 tokens to bob", async () => {
    await contractInstance.approve(ALICE, 100);
    await contractInstance.transferFrom(OWNER, BOB, 100, {from: ALICE});
    const balance = await contractInstance.balanceOf(BOB);
    assert.equal(Number(balance), 100, "Balance should be 100");
  });

This serialization exception should be fixed with the last commit to dev branch. Let me know if that fixes it for you. I think there may be logic problems with the eth_getLogs not returning anything, but you may not be running into that.

Has this been resolved for you?

No, still the same. I’ll try latest dev commit this weekend.
