Describe the bug
I followed the documentation,
const config = {
auth: {
authority: (process.env.REACT_APP_AUTHORITY as string),
clientId: (process.env.REACT_APP_AAD_APP_CLIENT_ID as string),
},
cache: {
cacheLocation: "localStorage",
storeAuthStateInCookie: true
},
};

and got a TypeError

Argument of type '{ auth: { authority: string; clientId: string; }; cache: { cacheLocation: string; storeAuthStateInCookie: boolean; }; }' is not assignable to parameter of type 'Configuration'.
Types of property 'cache' are incompatible.
Type '{ cacheLocation: string; storeAuthStateInCookie: boolean; }' is not assignable to type 'CacheOptions'.
Types of property 'cacheLocation' are incompatible.
Type 'string' is not assignable to type '"sessionStorage" | "localStorage" | undefined'. [2345]

I fixed it by import CacheLocation and casting my string
cacheLocation: ("localStorage" as CacheLocation),
