convert 0 rules but there are 1 rules from datasource . RuleCLass: FlowRule

sentinel convert 0 rules but there are 1 rules from datasource . RuleCLass: FlowRule

What caused this?

Could you please provide some detail information (e.g. your Sentinel version and use case)?

And please check whether your fastjson version is too low.

And provider your flow rule json, maybe the json is invalid.

我也遇到这个问题，环境说明：sentinel1.6.0版本
写了个demo，用于sentinel-dashboard写限流规则保存到nacos中，保存完以后，类似的规则是这样的：
[{
"app":"sentinel-learn",
"clusterConfig":{
"fallbackToLocalWhenFail":true,
"sampleCount":10,
"strategy":0,
"thresholdType":0,
"windowIntervalMs":1000
},
"clusterMode":false,
"controlBehavior":0,
"count":34,
"gmtCreate":1560935223271,
"gmtModified":1560935223271,
"grade":1,
"id":8,
"ip":"192.168.1.84",
"limitApp":"default",
"port":8720,
"resource":"user",
"strategy":0
}]
然后，启动一个springboot程序拉取nacos的限流规则，就出现这个错误
如果保存在nacos的限流规则是类似这样的
[{
"resource":"user",
"controlBehavior":0,
"count":2,
"grade":1,
"limitApp":"default",
"clusterMode":false,
"strategy":"0"
}]
就可以成功拉取过来
