system.tag.getConfiguration returns data even if the tags doesn't exist

Should I first do a readBlocking to check it?

It makes no sense that I'm getting data of a tag that doesn't exist.

Any idea?
Thx

Code
system.tag.getConfiguration("[ForTestRemove]root/fofdslder1/tadasg02", False)

Okey I just read that the returned data is this:

[
    {
        'path': [ForTestRemove]root/fofdslder1/tadasg02,
        'name': 'tadasg02',
        'tagType': Unknown  # <--
    }
]

So I guess the tagType is the one saying that didn't found the tag. I suposse that could work for me
