我是智能合约的新手。我无法从 Binance 测试网络读取智能合约。每次尝试使用 ethers.js 阅读我的智能合约时，我都会收到未处理的拒绝。
错误
未处理的拒绝（错误）：无效片段对象（argument="value", value=[{"inputs":[{"internalType":"address","name":"_owner","type":"address"} ,{"internalType":"string","name":"_name","type":"string"},{"internalType":"string","name":"_sr_number","type":"string "},{"internalType":"string","name":"_branch","type":"string"},{"internalType":"string","name":"_date","type": "string"},{"internalType":"string","name":"_grade","type":"string"}],"stateMutability":"nonpayable","type":"constructor"},{"inputs":[],"name":"branch","outputs":[{"internalType":"string","name":""," type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"date","outputs":[{"internalType ":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name ":"getName","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"grade","outputs":[{"internalType":"string","name":"","type":" string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"name","outputs":[{"internalType":"string ","name":"","type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"owner ","outputs":[{"internalType":"address","name":"","type":"address"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"sr_number","outputs":[{"internalType":"string","name":"","type":"string"}]," stateMutability":"view","type":"function"}], code=INVALID_ARGUMENT, version=abi/5.0.13)

我哪里错了？我已经使用工厂合同部署了合同。我使用的是合同的 ABI，而不是工厂合同的 ABI。
