Hello!
I have the same issue.
Lighthouse says “Browser errors were logged to the console” with the description: “TypeError: Failed to update a ServiceWorker for scope (‘https://axesslab.com/’) with script (‘https://axesslab.com/superpwa-sw.js’): An unknown error occurred when fetching the script.”.
Link to lighthouse report: https://googlechrome.github.io/lighthouse/viewer/?psiurl=https%3A%2F%2Faxesslab.com%2F&strategy=mobile&category=performance&category=accessibility&category=best-practices&category=seo&category=pwa&utm_source=lh-chrome-ext#best-practices
This is live at the moment at https://axesslab.com (but might remove SPWA if I can’t solve it.)
I was thinking that it could have to do with my CDN and the path is a missmatch. But double checked and seems fine.
Then thought maybe it could be my Content Security Policy, but made sure I use ‘self’ and CDN’s url. So not sure here…
