ERROR: CommunityAuthentication 'str' object has no attribute 'address'

[blueyed]

With version 3.0.0-beta1 I've seen this error:

This appears to prevent logging in:

I've added printing to it:

    def list_wallets(self) -> list[WalletInfo]:
        """Return public wallet info (no key material)."""
        print(self._get_node_wallets_list())
        return [
            WalletInfo(address=e.address, name=e.name, is_admin=e.is_admin)                                                                                                                                          
            for e in self._get_node_wallets_list()                                                                                                                                                                   
        ]                                                                                                                                                                                                            

which results in:

['e', '1', '0', 'b', '3', '4', 'a', '3', '6', 'a', 'a', '0', ...]

The storage appears to be a single string/address, while it is expected to be a list of dicts:

def _get_node_wallets_list(self) -> list[WalletEntry]:
        return [WalletEntry.from_dict(e) for e in self._storage.load()]

[blueyed]

`config.json contains:

       "wallets": {
            "evm": {
                "8453": "e10b34a36a..."
            }
        }

Hey @blueyed thanks for reporting. You have an old wallet format in your config.json. We don't migrate them automatically. Please remove the wallets entry in your config.json file and try again>

[blueyed]

Yeah, removing it fixed it.
