serviceWorker support?

Testing for ('serviceWorker' in navigator) appears to show support for them however when I try to register the service worker file I get the following error in the chrome developer/debugger:

Uncaught (in promise) DOMException: Failed to register a ServiceWorker: No URL is associated with the caller's document.

Has anyone figured out how to register service workers? Am I going down a rabbit hole?

Help! Thanks.

I believe I found the reason... it appears tizen (wearable) runs web apps from file:// and not a web server. serviceWorkers requires being served from a URL for security reasons. Am I understanding this correctly? Is there a workaround? :)

Another thought on the subject, can Concent Security Policies be used to allow service workers to run from file:// ?

I noticed I can set them in the config.xml file.

Hi,

at the end, did you find a solution? I'm in the same trouble. I'm developping a web app for smart TV and I want to use serviceWorkers but i have this error: "DOMException: Failed to register a serviceWorker: The document is in an invalid state".

If you serve the serviceWorker from an https web server, it will works?

Many thanks.

Hi, I'm also curious if you guys found a solution. I'm hitting the same issue as well, specifically, I get the original poster's error:
**ServiceWorker registration failed:  DOMException: Failed to register a ServiceWorker: No URL is associated with the caller's document.
