Deploying to Azure Linux Web App I get To import Sass files, you first need to install node-sass

Question

When I deploy my React App which was created using Create-React-App to Azure Web App on Linux I get the following when I browse to the website?

To import Sass files, you first need to install node-sass.

When I run this locally everything is fine (Running from a Mac). I have checked the DevOps deployment log and that reports it installed node-sass without issue. I have also tried to delete the node-sass folder in node_modules and npm install. This added node-sass again without issue but still I get the error?

Has anyone come across this before or have any suggestions?

This is the Yaml File.

I had a similar issue with another node package. In such cases where node packages do not get resolved try installing your node package globally using -g flag.
