Working on top of another extension

[miks2021]

Hello
Was trying to use this extension to get some data from the page using pre-script, and then send it to an external application, but got the error "Cannot run pre-script: Cannot access a chrome-extension:// URL of different extension"
The page is indeed generated by extension and has the url prefix chrome-extension://. But it seems like a bug, cause application doesn't throw an error, when no pre-script is run.
Can you look into this?

The extension ignores the pre-script when it cannot get executed. There is no way for this extension to access local pages including pages from other extensions.
