I could not find the below code in src/rpc/blockchain.cpp which was added in https://github.com/bitcoin/bitcoin/pull/19888/commits/97f4eb50b590422678f0ad5bb4f61cc45c97dd87:
```
    // The Genesis block does not have undo data
    if (pblockindex->nHeight == 0) return blockUndo;
```
EDIT: Just realized the pull request is still open. Sorry, I will close this.
