can someone help me with my JSON? I can't apply bold to the card title.

`"card":{ "*":{ "general": [{ "responsive": false, "keepLayerOrder": true }], "categoryLabels": [{ "show": false }], "title": [{ "show": true, "text": "Mon Titre", "fontSize": 12, "fontFamily": "Montserrat", "fontWeight": "Bold", "fontColor": {"solid": {"color": "#A13032"}}, "alignment": "center" }],

            "values": [{
                "fontFamily": "Montserrat",
                "fontSize": 15,
                "fontWeight": "Bold"
            }],
            "dataLabels": [{
                "show": false
            }]
        }
    },`

I tried adding the fontWeight: 'bold' property to the title in my JSON, expecting it to make the title bold. However, the title did not appear bold as expected. Instead, it remained in the regular font weight
