[Bug] Improperly encoded uint8 (enum) @ decoding constructor

[0x19]

There's an edge case with advanced use of constructor arguments.

Etherscan addr: https://etherscan.io/address/0x8e7e518b0481ADFaF969ED1f2B25bf553B79a677#code

Constructor ABI:

[{"inputs":[{"internalType":"address","name":"cvpToken_","type":"address"},{"internalType":"address","name":"reservoir_","type":"address"},{"internalType":"uint256","name":"anchorPeriod_","type":"uint256"},{"internalType":"struct UniswapConfig.TokenConfig","name":"TokenConfig","type":"tuple","components":[{"internalType":"address","name":"cToken","type":"address"},{"internalType":"address","name":"underlying","type":"address"},{"internalType":"bytes32","name":"symbolHash","type":"bytes32"},{"internalType":"uint256","name":"baseUnit","type":"uint256"},{"internalType":"enum UniswapConfig.PriceSource","name":"priceSource","type":"uint8"},{"internalType":"uint256","name":"fixedPrice","type":"uint256"},{"internalType":"address","name":"uniswapMarket","type":"address"},{"internalType":"bool","name":"isUniswapReversed","type":"bool"}]}],"outputs":[],"name":"","type":"constructor","stateMutability":"nonpayable"}]

Basically it results back with error failed to unpack values: abi: improperly encoded uint8 value

[0x19]

Potential root causes:

• Something in our Source Code -> AST -> IR -> ABI conversion is broken.
• Way we are trying to decode is broken.

I've checked and constructor bytecode passed for unpacking is correct. That's not issue.
