if (window?.sessionStorage?.getItem('accessToken')?.length > 0) {
this.navigateToApplication();
}
Encountering the following error:
Object is possibly 'undefined'.ts(2532)Any suggestions on how to resolve this issue? I am attempting to retrieve the value with optional chaining here.
An improved error message would be beneficial in this scenario. The issue lies in the fact that when
window?.sessionStorage?.getItem('accessToken')?undefined if the item is not present, your if comparison ends up being undefined | number > number, which poses a challenge from a type perspective.
To address this, you can simply remove the > 0 part since both undefined and 0 are considered falsy:
if (window?.sessionStorage?.getItem('accessToken')?.length) {
// Adjusted by removing `> 0`
this.navigateToApplication();
}
Alternatively, you can provide a default value using nullish coalescing (??):
if (window?.sessionStorage?.getItem('accessToken')?.length ?? 0 > 0) {
// Adjusted to include nullish coalescing
this.navigateToApplication();
}
window?.sessionStorage?.getItem('accessToken')?.length ?? 00 when the item is not found, allowing for a valid number > number comparison that satisfies TypeScript.
One issue to address is the possibility that
window.sessionStorage.getItem("accessToken") const accessToken = window.sessionStorage.getItem("accessToken");
if (accessToken && accessToken?.length > 0) {
this.handleAccessToken();
}
