Exception handling request to /unifyInterface/unifyApi org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.alibaba.fastjson.JSONException: syntax error, pos 111, line 1, column 112{"buyerName":"wwz","buyerType":"01","totalAmountTax":"100","manualOrderDetails":[{"amount":"","invoiceNature":,"itemName":"","itemTaxCode":"","taxIncluded":"","taxRate":"","yhzcbs":""},{"amount":"","invoiceNature":,"itemName":"","itemTaxCode":"","taxIncluded":"","taxRate":"","yhzcbs":""},{"amount":"","invoiceNature":,"itemName":"","itemTaxCode":"","taxIncluded":"","taxRate":"","yhzcbs":""},{"amount":"","invoiceNature":,"itemName":"","itemTaxCode":"","taxIncluded":"","taxRate":"","yhzcbs":""}]}是什么错误怎么解决

这个错误是由于 JSON 格式错误导致的，具体错误信息是 "syntax error, pos 111, line 1, column 112"，意思是在第 1 行第 112 列出现了语法错误。可能是在 JSON 字符串中某个地方缺少了引号或者逗号，或者是数据类型不匹配等问题。

要解决这个问题，需要检查你的 JSON 字符串是否符合标准的 JSON 格式，可以使用一些在线的 JSON 格式化工具检查和修复 JSON 格式，例如 JSONLint，或者使用一些工具库来解析 JSON 字符串并找到问题所在。此外，也需要检查你的代码中是否有错误，例如变量名拼写错误等问题。

这个错误通常是由于请求中缺少multipart boundary导致的。multipart boundary是指在multipart/form-data格式的请求中，用于分隔各个part的标识符。你可以检查一下你的请求头中是否包含了正确的Content-Type和boundary参数。另外，也可以尝试使用其他工具或者库重新构造请求，确保请求中包含了正确的multipart boundary。如果你需要更具体的帮助，可以提供更多的上下文信息，我会尽力帮助你解决问题。
