我正在尝试在反应中使用延迟加载。我从 react 中导入了 lazy 和 Suspense 组件。该页面不再显示任何内容。但我得到的错误是：
预期动态 import() 调用的结果。而是收到：[object Object]。元素类型无效。收到解析为：未定义的承诺。Promise 元素必须解析为类或函数。
这是 SibaCard 组件
export class SibaCard extends React.Component<ICardProps, ICardState> {
constructor(props: ICardProps) {
super(props);
this.state = {expanded: true};
}
expandChange = () => {
this.setState((prevState: any) => ({ expanded: !prevState.expanded }));
}
style = {
headerStyle: {
borderBottom: "2px solid #258ECB",
marginBottom: "1em",
background: "linear-gradient(rgba(0,0,0,0.0),rgba(0,0,0,0.02))"

expanded={this.state.expanded}
expandable={false}
containerStyle={this.style.containerStyle}
onExpandChange={this.expandChange.bind(this)}

我不知道我做错了什么,也许我没有把小数点好.
private static decimal ReturnPayments(decimal loanAmount, int durationMonths, decimal interestMonthly)
{
return (loanAmount * interestMonthly)/ (decimal) (1-Math.Pow((int)(1
+ interestMonthly), -durationMonths));
}
public IEnumerable<LoanRepaymentSchedule> GetRepayment(string employeeId, decimal principalAmt, decimal rate, int terms)
{
var employee = _employeeService.FindByAsync(e => e.Id == employeeId
&& e.Status == EntityStatus.Active).Result;
var results = employee.FirstOrDefault();
var currentBalance = principalAmt - 0;
decimal monthlyRate = rate / 1200;
var monthlyPaymentAmt = ReturnPayments(currentBalance, terms, monthlyRate);
var result = new List<LoanRepaymentSchedule>();
