Application Insights JS trackException shows "Failed method: 'Unkown'"

I'm experimenting with AppInsights and use the following code: (fetch fails with a 500 reply)

private callMethod(): void {
  this._callMethodInternal();
}

private async _callMethodInternal(): Promise<void> {
  try {
    await fetch("https://localhost:44369/api/values", {
      method: "GET",
      headers: {
        Accept: "application/json",
        "Content-Type": "text/json"
      }
    });
  } catch (err) {
    AppInsights.trackException(err);

    throw err;
  }
}

The exception is shown in Application Insights, but the "Failed method" property shows "Unknown" as value. Is there a way to show the correct method name?

Thanks

The type of object expected by trackException is IExceptionTelemtry rather than a native Error object. In other words, you can't pass the caught error directly to trackException.

The API reference outlines all of the IExceptionTelemtry properties, but the most important is the exception property, as it is required.

Example:

try {
  // logic that throws
} catch (error) {
  AppInsights.trackException({ exception: error });
}

you are not passing proper params. Follwoing is the updated method

trackException(exception: Error, handledAt?: string, properties?: {[string]:string}, measurements?: {[string]:number}, severityLevel?: AI.SeverityLevel)

For reference, check following link https://github.com/microsoft/ApplicationInsights-JS/blob/master/API-reference.md
