In my SPFx webpart, I am utilizing PnPJS to set custom item level permissions on specific items within multiple lists. Below is the snippet of code I have written:
let listIds: string[] = [
"LISTGUID1",
"LISTGUID2"
];
for (const listId of listIds) {
const listItems: Item[] = await sp.web.lists
.getById(listId)
.items
.filter(`LookupFieldId eq ${lfId}`)
.get();
if (Validate.ArrayWithElements(listItems)) {
for (const item of listItems) {
await item.breakRoleInheritance(false);
await item.roleAssignments.add(userId, roleDefId);
}
}
}
An error occurs at this line:
await item.breakRoleInheritance(false, false);The error message displayed is:
Uncaught (in promise) TypeError: item.breakRoleInheritance is not a function
I have also attempted explicitly casting the result to type Item, but it still does not work. The Item class extends SharePointQueryableShareableItem, and SharePointQueryableShareableItem extends SharePointQueryableSecurable. The method is defined in the latter.
