Trying to follow this guide: https://learn.microsoft.com/en-us/azure/digital-twins/quickstart-adt-explorer

After downloading the .zip, and running 'npm install', 'npm run start', the expected browser pops up. Trying to upload new model from sample.zip causes this error: 

   *** Error fetching models: RestError: Error "SyntaxError: Unexpected token E in JSON at position 0" occurred while parsing the response body - Error occured while trying to proxy to: localhost:3000/models?api-version=2020-05-31-preview&dependenciesFor=&includeModelDefinition=true.

I've tried restarting reinstalling and updating. Cannot figure out a fix.

@António Sérgio Azevedo - Read through the suggested thread but was not able to get progress with Digital Twins ADT app. Same error. However, I was able to run ADT on a another computer. Unsure why my PC is not working - still investigating.
