Removing mulitple lines

I am trying to write up a command line interfaces that will removes a particular section / lines of codes within a list of json files. By the way, the json file are located within the sub-folders of the main directory

I am pretty new to this but this is the code that I can come up with so far - find -name "*.json" | xargs sed -i "map" but some of the json files I had, its format is slightly different

So far I am seeing the following 2 formats within my list:

{
    "tags": {}, 
    "map": {
        "KPA": {
            "State": True, 
            "namespace": "KPA01"
        }
    }
}

or

{
    "tags": {
        "type": [
            "char"
        ], 
        "dynamic": true
    }, 
    "map": {
        "KPA01": {
           "State": True, 
            "namespace": "KPA01"
        }
    }
}

and basically, I am trying to omit out the map section that it has, so that it will only display the tags section but the presence of commas and [] / {} are making it hard for me. So my output results should be like this:

{
    "tags": {}
}

or

{
    "tags": {
        "type": [
            "char"
        ], 
        "dynamic": true
    }
}

Will this be possible to do so in a command line interface? I heard that jq may be able to do it, however, as I tried executing jq '.map' test.json I am getting parse error: ':' not as part of an object at line 2, column 11 in my terminal. Likewise it also seems to be giving off error if I am using the jq play online..

Any ideas?
