[Transaction Builder] Parameter input error

[edgelang]

Bug description

I'm using the contract ABI to construct a transaction in the Safe wallet, but one of the object array parameters consistently fails validation, even though the same parameters work for contract calls on Etherscan. I suspect there might be an issue with the input validation. The error message does not provide specific details. I think this needs to be optimized.
