Hi All,

I am trying to create a Lightning Web Component for a salesforce community in Visual Studio but I believe that there is an issue with my JS somewhere that is causing it to fail.

I also plan on having an input parameter in the compontent and use a key/value pairing to replace the placeholder account for the twitter feed based upon the user defined input, but that is not currently fully configured.

JS

import { LightningElement, api, } from 'lwc';
import { loadScript } from 'lightning/platformResourceLoader';
import Twitterjs from '@salesforce/resourceUrl/Twitterjs';

export default class Twitter extends LightningElement {

    Twitterjs = false;

    renderedCallback() {
        if (this.Twitterjs) {
            return;
        }
        this.Twitterjs = true;

        Promise.all([
            loadScript(this, Twitter + 'twitter.js'): Promise
        ])
            .then(() => {
                this.Twitterjs();
            })
            .catch(error => {
                this.dispatchEvent(
                    new ShowToastEvent({
                        title: 'Error loading Twitter',
                        message: error.message,
                        variant: 'error'
                    })
                );
            });
    }
@api twitterhandle
}

HTML

<template>
    <lightning-input-field field-name="twitterhandle"></lightning-input-field>
    <a class="Twitter" lwc:dom="manual" data-height="500" data-theme="light" href="https://twitter.com/TwitterDev?ref_src=twsrc%5Etfw" data-chrome="nofooter noborders">Tweets by TwitterDev</a>
</template>

                <supportedFormFactor type="Small" />
            </supportedFormFactors>
    </targetConfig>
</LightningComponentBundle>

It would be great if anyone could point out any glaring errors as I have been troubleshooting this for a number of hours now without any success.

Thanks,
