Whether the results returned by chrome.webNavigation.getAllFrames contain undocumented properties

[tom mak]

At the beginning, when my product was executed through chrome.tabs.executeScript on the user's computer, I found that the callback function would not be called. 

When using other products with similar functions, I found that the function was normal. After analyzing the product, I found that before execution, it determines whether the result returned by chrome.webNavigation.getAllframes contains the crossOriginError attribute, but it is not recorded in the official documentation, so is this attribute indeed effective at some point?

Hi Tom,

I'm not familiar with that property, and I don't see it in a Google search or a quick look at our source code.

Perhaps some other code within the extension was setting this property?

Either way, I wouldn't expect it to be returned today.

Thanks Reply!

Continuing to analyze the code, I found that it also judged the errorOccurred attribute, which was indeed not judged in my code
