Landsat Explorer, Landsat Viewer, EO Explorer: Fix Identify widget to accommodate for thermal bands in Landsat image service

Seeking assistance with building customized version of Lansat Explorer App (SOS)

Hi all,

If this isn't permitted, I'll remove.

I'm seeking someone who'd be willing and able to help me with building a customized version of the Landsat Explorer app. I'm finishing my certificate program in GIS this year. I'm on a tight deadline to complete my capstone project by the end of Nov, 2022 (with a report and presentation). I've been reading through ArcGIS Developers for guidance and watching videos but am struggling still to make good progress on this. Help would be much appreciated as I'm not familiar with ArcGIS API for Javascript. If you're wiling to be a tutor, I'm happy to discuss an appropriate arrangement.

Sincerely,
Cassidy

Error deploying widgets from Landsat8 Explorer app

I tried to deploy widgets from Landsat8 Explorer app on WAB and the error appeared. This occurs with some of the widgets i.e. Mask, ISCompare and ISChangDetection.
When I tried adding ISChangeDetection, this error appeared:

From my understanding, it can't find .png image in the following page right?
Please help correct me if I'm wrong.

When I tried adding Mask and ISCompare widget, another error appeared:
Error: scriptError: ./resourceLoad.js?wab_dv=2.16
From what I understand, there's something wrong with the script.

The steps of adding widget is as followed: https://enterprise.arcgis.com/en/portal/latest/use/add-custom-widgets.htm
Please be notified that I am no programmer.
Does additional script have to be written in order for this to work?
Or is it possible to deploy just widgets, but not the app itself (Landsat8 Explorer)?
Please help advise on this.

Configure image service and AGOL account

We downloaded and deployed the web app following instructions.

Looking at the config file we noticed that the image service URL is empty (while Landsat explore is preconfigured to ponit at Esri landsat image services)

So we add the following URL "https://sentinel.arcgis.com/arcgis/rest/services/Sentinel2/ImageServer "and it works.
but when we try to use the time selector widget a " NaN undefined NaN " error apepar in the form (see attached image).

We have seen that this feature depends on AGOL account so we sign in with our subscriprion credential but the error continue to appear.

Looking at network traffic (by firebug) we noticed a worning regarding AGOL credential and token ..

Please could you give us help and a correct sample of config file settings ?
thank you
Enrico

Added Landsat Viewer app
