I have been struggling with this error for quite sometimes and I am wondering if someone could help me get this running

I have

[Edit: apparently this file looks similar to h5 format] I am trying to extract metadata from a file with extension of (.dm3) using hyperspy in Python, I am able to get all the data but it's getting saved in a treeview, but I need the data in Json I tried to make my own parser to convert it which worked for most cases but then failed:

I'm working on a Chrome extension that integrates with a website. My users can do actions on this website when they are logged in to it.

I have a Socket.IO server that delivers commands to my Chrome extension. Once a command arrived, the extension invokes a local function from the host website. Then, the host website, which has an authenticated active session with its own API, will invoke some update/insert call.

I recently realized a potential security issue, which is - if anyone spoofs my server address on my extension clients organization, he can easily abuse it to send his own parameters on behalf of my server (image 2).

Is there any smart way to ensure my client communicates with the real server and not an imposter?

If so, how do I enable Vue debugger for extensions?

I face that problem only when I use input function; otherwise it works properly. This problem occurred only in Visual Studio Code, while if I work on Python champ the same code works properly.

I'm trying to follow the Google Style of docstrings, but I'm not sure how to document a function (and the class itself) when there's functions that add/supdates an attribute. Currently I have something like this:
