Error in Helpfunctions

[Ca-Pe-21]

An error in the help functions leads to the deletion of the Webuntis object tree.

The functions deleteOldInboxObject and deleteOldNewsFeedObject do not delete individual objects from Inbox or News, but rather a large part of the Webuntis object tree.

deleteOldInboxObject
await this.delObjectAsync(index.toString(), { recursive: true });
replace with
await this.delObjectAsync('inbox.' + index.toString(), { recursive: true });

deleteOldNewsFeedObject
await this.delObjectAsync(index.toString(), { recursive: true });
replace with
await this.delObjectAsync('newsfeed.' + index.toString(), { recursive: true });
