[WSO2 API管理员，验证刷新令牌时出错

Question

我已经设置了一个带有SQL Server作为主要用户存储的WSO2 API管理器。并且我们已经在其中配置了API列表。验证刷新令牌错误时，我们经常会收到错误消息。可能是什么原因？

您需要在/repository/conf/datasources/master-datasources.xml中的数据源配置中设置SendStringParametersAsUnicode参数更改指向MSSQL数据库的数据源上的datasource url参数，

<url>jdbc:sqlserver://MSSQL_URL:5023;databaseName=SSO_INTERNAL_540;encrypt=true;trustServerCertificate=true;SendStringParametersAsUnicode=false</url>

here中详细解释了MSSQL JDBC驱动程序此参数的详细信息。
