生产环境调用Xero API创建报价报Generic Error 500，开发环境正常

我在开发环境使用开发者组织可正常运行，也通过Xero PHP SDK API成功运行过独立线上项目，但将相同代码部署至待上线生产环境时，创建报价出现棘手的Generic Error 500：

prod.ERROR: XeroAPI\XeroPHP\ApiException: [500] Server error: PUT https://api.xero.com/api.xro/2.0/Quotes?summarizeErrors=true resulted in a 500 Internal Server Error response:
{"Title":"An error occurred","Detail":"An error occurred in Xero. Check the API Status page <a href="http://status.developer.xero" rel="nofollow noreferrer">http://status.developer.xero (truncated...)

我已确认请求内容无误，且在开发环境运行完全正常。唯一区别是生产环境使用正式账户中的真实客户ID，这可能是问题根源吗？Xero账户中是否存在阻止通过API为客户创建报价的设置？

我在令牌初始化和刷新方面无问题，接下来该排查什么？

以下是development.xero日志历史中的请求体（敏感GUID已修改）：

排查方向 #

• 检查真实客户账户状态：确认该客户在正式账套内是否正常，无禁用、合并或未验证状态。
• 验证税码与科目匹配：确认INPUT2税码在正式账套中存在，且和200科目代码的配置兼容。
• 确认BrandingThemeID有效性：生产环境的主题ID与开发环境不通用，需检查该ID在正式账套中是否存在且可用。
• 字段长度与特殊字符检查：正式账户可能对Terms、Summary等字段的长度限制更严格，同时确认英镑符号£是否编码正确。
• 获取完整错误详情：确保请求的summarizeErrors=true参数生效，开启SDK详细日志，获取未截断的错误信息。
• 检查账套权限：确认API令牌对应的用户在正式账套中拥有创建报价的权限，尤其是针对该客户的操作权限。
• 测试极简请求：先发送仅含必填字段（ContactID、LineItems、Date）的报价请求，逐步添加字段定位问题。
