Aave Flashloan `reverted with reason '73'`

Question

I'm getting an error when attempting to execute an Aave V2 Flashloan within a Hardhat-mocha test while connected to a fork of the Kovan network. It's unclear to me what revert reason "73" corresponds to.

Aave has an error code mapping available on their documentation website, which basically mirrors what is in their protocol repository:

• https://docs.aave.com/developers/guides/troubleshooting-errors
• https://github.com/aave/protocol-v2/blob/master/contracts/protocol/libraries/helpers/Errors.sol
