    actully i was used dynamic form in react, i want to save this data,please help me how can i solve this issue??

CodePudding user response：

for solve this kind of issue you need to verifyyour code ,is any _id already declare in your react this.State?? if you have declared any _id which do match your database response like this _id then go to your code simply modify it or remove it then try it again. that will be work
