logs decoded:

event ReportNFTMinted(address indexed recipient, uint256 indexed newItemId, string reportName, uint256 startTime, uint256 endTime); , event Transfer(address indexed from, address indexed to, uint256 indexed tokenId);

data decoded, you have to provide ABI and use ethers.js to decode it:

字符串偏移量：偏移量為192個字符（96字節）。 reportName 字符串的數據從第192個字符開始。

startTime 解析：解析後的 startTime 值為 1704959618（十進制）。

endTime 解析：解析後的 endTime 值為 1704959620（十進制）。

reportName 字符串長度：字符串長度的十六進制表示為 '0000000000000000000000000000000000000000000000000000000000000042'。轉換為十進制後，這表示字符串長度是 66 個字符。

reportName 字符串內容：解析後的字符串內容是 '0x7365636f6e645f7265706f727400000000000000000000000000000000\x00\x00\x00\x00\x00\x00'。這個十六進制串代表 "second_report"，伴隨著一些填充的零。
