KeyError: None

How can it be fixed?

Looks like the Royalties contract has this opcode setup weird

"268": {
    "dev": "Cannot send ether to nonpayable function",
    "fn": "<unknown>",
    "offset": null,
    "op": "REVERT",
    "path": null
},

the "path": null is why we get a key None.

This is where the error happens:

    def _generate_revert_map(self, pcMap: Dict, source_map: Dict, language: str) -> None:
        # Adds a contract's dev revert strings to the revert map and it's pcMap
        marker = "//" if language == "Solidity" else "#"
        for pc, data in (
            (k, v)
            for k, v in pcMap.items()
            if v["op"] in ("REVERT", "INVALID") or "jump_revert" in v
        ):
            if "path" not in data:
                continue
            path_str = source_map[data["path"]]

Basically: path IS in data, but its value is None, which isn't a key in source_map.

I am working around the issue with this:

            # if "path" not in data:
                # continue
            if not data.get("path"):
                continue
            path_str = source_map[data["path"]]

Attached the contract in question. RecordLabel.txt

Any way to get around this without modifying the Brownie source? Perhaps in the config?
