task fields are not displaying value in LWC, which is used in partner community

I have created LWC, which is having controller to fetch task records from apex controller. but it is again giving me same error “Object Task is not supported in UI API“. can any one please let me now what is wrong in this code.

js file:

import { LightningElement, api, wire, track } from 'lwc';
import { getSObjectValue }                    from '@salesforce/apex';
import GetTaskRecords                         from '@salesforce/apex/FetchTaskLWCController.GetTaskRecords';
import task_Object                            from '@salesforce/schema/Task';
import Task_Assigned_To                       from '@salesforce/schema/Task.OwnerId';
import Task_Status                            from '@salesforce/schema/Task.Status';
import Task_Priority                          from '@salesforce/schema/Task.Priority';
import Task_Due_Date                          from '@salesforce/schema/Task.ActivityDate';
import Task_Type                              from '@salesforce/schema/Task.Type';
import Task_Related_to_Account                from '@salesforce/schema/Task.WhatId';
import Task_Subject                           from '@salesforce/schema/Task.Subject';
import Task_Comments                          from '@salesforce/schema/Task.Description';


export default class ApexWireMethodToFunction extends LightningElement {
    @api TaskRecord;
    @api recordId;
    @track tasks;
    @track error;

    taskObject = task_Object;

    @wire(GetTaskRecords, {Id: '$TaskRecord'})
    task;

    get assignedto() {
        return this.task.data ? getSObjectValue(this.task.data, Task_Assigned_To) : '';
    }
    get status() {
        return this.task.data ? getSObjectValue(this.task.data, Task_Status) : '';
    }
    get priority() {
        return this.task.data ? getSObjectValue(this.task.data, Task_Priority) : '';
    }
    get duedate() {
        return this.task.data ? getSObjectValue(this.task.data, Task_Due_Date) : '';
    }
    get type() {
        return this.task.data ? getSObjectValue(this.task.data, Task_Type) : '';
    }
    get relatedtoaccount() {
        return this.task.data ? getSObjectValue(this.task.data, Task_Related_to_Account) : '';
    }
    get subject() {
        return this.task.data ? getSObjectValue(this.task.data, Task_Subject) : '';
    }
    get comments() {
        return this.task.data ? getSObjectValue(this.task.data, Task_Comments) : '';
    }

    wiredTasks({ error, data })
    {
        if (data) 
        {
            this.tasks = data;
            this.error = undefined;
        } else if (error) 
        {
            this.error = error;
            this.tasks = undefined;
        }
    }
}

Controller :

 public with sharing class FetchTaskLWCController
{
    @AuraEnabled(cacheable=true)
    public static List<Task> GetTaskRecords() 
    {
        return [SELECT Id, OwnerId, Status, Priority, ActivityDate, Type, WhatId, Subject, Description FROM Task];
    }
}

As task and event are unsupported objects in UI API, so took apex controller approach.
