Aurelia TS pulling map from a map - aurelia

Question

I have a Map<string, Map<string, boolean>> defined in my appConfig.json and when I try and get values from the map using .get() I get an error that it is not a function.
This is in my appConfig.json
"rolePermissions" : [
{"name" : "Admin", "value" : [
{"name" : "customerList", "value" : "true"},
{"name" : "customerDetails", "value" : "true"},
{"name" : "addCustomerUser", "value" : "true"},
{"name" : "editCustomer", "value" : "true"},
{"name" : "updateBackend", "value" : "true"},
{"name" : "createCustomer", "value" : "true"},
{"name" : "jobsList", "value" : "true"},
{"name" : "jobsView", "value" : "true"},
{"name" : "jobsEdit", "value" : "true"},
{"name" : "jobsDownload", "value" : "true"},
{"name" : "usersList", "value" : "true"},
{"name" : "usersEdit", "value" : "true"},
{"name" : "usersDelete", "value" : "true"},
{"name" : "usersCreate", "value" : "true"}
]}
and I have set the property in my appConfig.ts as:
public rolePermissions: Map>;
This is how I'm accessing rolePermissions:
let rolePerms = this.appConfig.rolePermissions;
let rolePerm = rolePerms.get("Admin");
When I try and pull the "Admin" value from the map I get an error:
ERROR [app-router] TypeError: rolePerms.get is not a function

EDIT:
I didn't catch that you file is a json, the original post still applies though.
If you cannot convert your rolePermissions to a Map, you'll need to process it like a regular array:
rolePerms.find(x => x.name === "Admin").value
ORIGINAL:
The way you initialize rolePermissions is your problem.
You're actually not creating a Map, but an Array.
Therefore the function get is not available, since get is not a function defined on the array prototype.
Here's how you'd need to do it:
const rolePermissions = new Map<string, Map<string, boolean>>(
[
[
"Admin", new Map<string, boolean>([
["customerList", true],
["customerDetails", true],
["addCustomerUser", true],
["editCustomer", true],
["updateBackend", true],
["createCustomer", true],
["jobsList", true],
["jobsView", true],
["jobsEdit", true],
["jobsDownload", true],
["usersList", true],
["usersEdit", true],
["usersDelete", true],
["usersCreate", true]
])
]
]);
