This should fix from API side. getNodeTemplate API is providing this reponse for user field

"user": {
                "metadata": {
                    "label": "User",
                    "description": "Database username"
                },
                "types": [
                    {
                        "fieldType": "TEXT",
                        "ballerinaType": "string",
                        "selected": false
                    },
                    {
                        "fieldType": "EXPRESSION",
                        "ballerinaType": "string?",
                        "selected": false
                    }
                ],
                "placeholder": "()",
                "optional": true,
                "editable": true,
                "advanced": true,
                "hidden": false,
                "codedata": {
                    "kind": "DEFAULTABLE",
                    "originalName": "user"
                },
                "defaultValue": "()" // print this
            }

The root cause for this issue is the resolved package being null at the time of extracting the parameter info in the function databuilder. This will be fixed via ballerina-platform/ballerina-language-server#660
