problem description
found a strange problem that the polling request could not be called
the environmental background of the problems and what methods you have tried
when I was polling to call a method, I found that the code could not run into the body of the method (upInitialize is the method that was called by polling), and I could not output the first line of console in the method. When I removed the respondsJudge, everything was normal again after the method called (if (res)).

/ / Please paste the code text below (do not replace the code with pictures)
/ / call the polling method
componentDidMount() {
this.initialize();
loopReq("abcd",this.upInitialize);
}
//
upInitialize =() =>{
energyStorageInformation_img()
.then(res => {
if (respondsJudge(res)) {
this.setState({ energyStorageInformation_img: res.data.storageInfo })
}
});
}
//respondsJudge
export function respondsJudge(res){
return res
}
//
export function loopReq(timerName,reqFn){
window.myTimer = window.myTimer? window.myTimer:{};
window.myTimer[timerName]=window.setInterval(()=>{
reqFn();
},Config.dataTimer);what result do you expect? What is the error message actually seen?
I wish I knew why
