im using 7.7 and have just pulled an existing website into a new visual studio project as i can deploy it to azure webapps using azure devops. the site works exactly as before (with the media now on azure blob storage) but i have one problem

when enable the minification and bundling by setting debug="false" the admin console is no longer usable. initally i was getting a 404 on a css bundle so i removed css fro mthe bundling and just left the JS in then the css download fine as individual files as did the js but once downloaded i was getting 'unexpected identifier' in the chrome console on click this took me to "use Strict"

so in short everything works if in debug but not when in release

I have tried:

1. clearing the cache
2. incrementing the version in the client config
3. looking in the event log the only thing i can find their is the following (frequently)

ImageOptimizerWebJob.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.ArgumentNullException

any suggestions as im now at a loss as to how to get this working

many thanks
