I just enabled gzip http compression on Azure IIS. I'm serving an AngularJS webpage. I suddenly got:
Could not find Angular on page
on every single protractor e2e test I have in place
gzip compression is enabled, on my local environment everything works
Actually, gzip compression is enabled by default without any operation, you can refer to the answer of Azure Web App Not Using GZip Compression and gzip compression in Windows Azure Websites.
According to your error message, it seems that there is a path issue of the Angular library file. Could you double check your js libraries path, or could you please share your code/project structure with us for further troubleshooting?
