Error: Unsuported TypeName node type: FunctionTypeName at serializeTypeName (node_modules/@openzeppelin/upgrades-core/src/utils/function.ts:43:13)

See original GitHub issue

Compiling a big project and this error came up, can’t trim down the error but i think it relates to me using function type in a library:

	function updateVault(
		Vault.Data memory vaultData,
		address TAddr,
		function(
			address,
			uint256,
			uint256,
			uint256,
			uint256,
			uint256
		) external onVaultUpdate
	) internal {
}

This happens on 0.8.4 solidity and "@openzeppelin/hardhat-upgrades": "^1.9.0"

So I see you have some external functions with functions arguments. This is something we clearly didn’t expect. It is not an issue with internal functions, but it is with external functions as we do save signatures to future-proof the manifest a bit more.

Hopefully, the fix is very simple (see #407). I’ll double-check that with @frangio and we should have a new version released soon!

Should be fixed on @openzeppelin/upgrades-core@1.8.1.
