Sonar scanner with SonarJS fails to parse typescript

Question

I am using SonarQube Scanner 3.3.0.1492, with the SonarJS 5.2.1.7778 (javascript) plugin. I did a yarn install to install typescript v3.5.3. When I run the sonar scanner, I receive a couple of different parse errors for things that normally parse properly during our builds. Here are a couple of examples

 const genericGatewayRequest = <T extends {} | void>(request: AxiosRequestConfig): AxiosPromise<T> => {
                                          ^
 const mockedAxios = Axios as jest.Mocked<typeof Axios>;
                           ^
 declare module 'react-number-format' {
    export interface NumberFormatProps extends Partial<FormOutlinedTextFieldProps> {
    ^

Most of these appear to be newer features of typescript. So I'm wondering which part of my setup is out of date? I don't understand how sonar-scanner gets its configuration for typescript.

For extra context here is my sonar-project.properties

sonar.exclusions=node_modules/**
sonar.projectKey=membexxxxxxxxxx
sonar.sources=. 
sonar.host.url=https://stl-wxxxxxxx

And here is my tsconfig.json
