Postman 在运行多请求api之后，api不会在迭代中运行

/api/stores

在postman中触发不同数据的数组：

#pre-request script

var managers= pm.globals.get("managers");
var ref= pm.globals.get("ref");
if(!managers && !ref){
     managers=[0,1];
    ref=["QA0","QA1"];

}


var currentmanager=managers.shift();
pm.globals.set("manager",currentmanager);
pm.globals.set("managers",managers) ;

var currentref=ref.shift();
pm.globals.set("refeng",currentref);
pm.globals.set("ref",ref) ;


#Test script

var managers=pm.globals.get("managers");
var ref=pm.globals.get("ref");
if(managers && managers.length>0 && ref && ref.length>0){
    postman.setGlobalVariable("currentmanager",managers.shift());
    postman.setGlobalVariable("currentref",ref.shift());
    postman.setNextRequest("https://staging-api.toters-api.com/api/stores");
}
else{
    postman.clearGlobalVariable("manager");
     postman.clearGlobalVariable("managers");
      postman.clearGlobalVariable("ref");
    postman.clearGlobalVariable("refeng");
}

但是当在2次迭代中运行所有api时，在

/api/stores

下运行的所有api都不会在第2次迭代中运行
