bug: misleading error message

[carmen0208]

Describe the bug
When I followed the LayerZero OFT quickstart guide using npx create-lz-oapp@latest --example oft and then ran the npx hardhat lz:oft:send ... command, I encountered an error.

The root cause was that I forgot to mint tokens, but the error message pointed me in the wrong direction

To Reproduce
Steps to reproduce the behavior:

1. following the instruction of https://docs.layerzero.network/v2/developers/evm/oft/quickstart
2. finish all the preconfiguration. but do not mint any token
3. run lz:oft:send will gets the error message

Expected behavior
Not show the misleading OFT: undefined message

Screenshots

Environment (please complete the following information):

• OS: macOS
• OS Version Sequoia
• VM: node
• VM Version: v20.14.0

Additional context
