How to set initializationOptions in the LSP client setting?

Help

I had a problem where the autocompletion added another period after I typed a property of a Javascript object and pressed enter.

Expected output:

const test = {
    property: 1
};

// before autocompletion
test.

// after autocompletion
test.property

After output:

const test = {
    property: 1
};

// before autocompletion
test.

// after autocompletion
test..property

I was following a solution from a Github issue thread. It suggested to add a setting, specifically “completionDisableFilterText”, to “initializationOptions”. I opened settings.json and add some lines in the “javascript” entry like this:

        "javascript": {
            "command": ["typescript-language-server", "--stdio"],
            "rootIndicationFileNames": ["package.json", "package-lock.json"],
            "url": "https://github.com/theia-ide/typescript-language-server",
            "highlightingModeRegex": "^JavaScript.*$",
            "documentLanguageId": false,
            "settings": {
                "completionDisableFilterText": true,
                "filterText": true
            },

            "initializationOptions": {
                "completionDisableFilterText": true,
                "filterText": true
            },
            "completionDisableFilterText": true,
            "filterText": true
        }

However, the problem is still there; it still adds another period. How do I add an “initializationOptions”?
