sync-diff报"the isEqual1 and isEqual2 cannot be both true错误

谢谢，请问default snapshot具体是怎么设置？没有找到相关资料。下面这些算吗？

[data-sources.tidb_prd]
host = “xxxx”
port = xxxx
user = “xxxx”
password = “xxxx”
snapshot = “433408135904886975”

[data-sources.ubisql_prd]
host = “xxxx”
port = xxxx
user = “xxxx”
password = “xxxx”
snapshot = “433408135942111294”
