Web Client Extension Error - React App

[christine_01]

Hey everyone,

I have created a React App for the purpose of deploying it on the Web Client. I followed the instructions on SAPs documentation "How to Develop Web Client Extensions" in order to package and deploy it. However when I click on its tile in the web client I get the following error:

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Tue Oct 17 11:38:02 EEST 2023There was an unexpected error (type=Not Found, status=404).
Any ideas on what I should look out for in my code in order to troubleshoot it?
Thank you in advance.

Could you go to the browser development console, and find out which request has the 404 error?
