Edge extension: Validation failed for extension manifest

Question

After the review of my Edge extension I got the approval to submit it into the store. However the submission failed with this error.

File specified by 'background.page' does not exist: Extension\PopupApplication\app\index.html?background=1

Validation failed for extension manifest: Extension\manifest.json

The relevant part in the manifest.json looks like:

"background": {
    "page": "PopupApplication/app/index.html?background=1",
    "persistent": true
}

It seems like the validation does not allow query parameters in the background.page property. But my logic requires the parameter. Is there any workaround for this or do I have to change my app logic?

The Edge extension works fine locally. Also it works for Chrome and Firefox. I have used the Microsoft edge Extension Toolkit to port the Chrome extension.

Edit: The simplified folder structure looks like the following

+ Assets
+ Extension
|----+ PopupApplication
     |----+ app
     |--------+ index.html
|----+ manifest.json

please check the page path, from the error message, it seems that it can't find the page. — Zhi Lv
@ZhiLv-MSFT I am sorry, I had a typo. I did an edit for clarification. My guess is that the validator interprets index.html?background=1 as a filename. — afrischk

The fix was to change our code to successful submit the edge extension. The submission does not allow query parameters in the background.page property. This was confirmed by the Microsoft support.
