我正试图在Superset中获取仪表板，但遇到以下错误：
ERROR:root:Expecting ',' delimiter: line 1 column 106 (char 105)
上面的错误是我跟踪吊舱时发生的。
在前端，我只看到：An error occurred while fetching dashboards.
完整的堆栈是：

我试着查看数据库中的dashboards表，但没有发现任何异常。我尝试加载仪表板页面(/ddashboard/list/(，得到了与上面相同的JSON错误。
在我的数据库中，我试图在published列下将所有仪表板标记为false，即使错误也没有消失。
在仪表板表中的1行或所有行中，json_metadata列似乎已损坏。我会努力弄清它失败的原因(看起来是这条线(。您可以尝试针对数据库运行超集的开发版本，并在失败的地方添加一些日志记录。您还可以尝试检查该表中的json_metadata列(尝试将其提供给python-json解析器(，看看是否可以识别导致json.loads函数失败的问题。
