[BUG] Angular-Typescript - Uninitalized Authorization queryParameters

Created by: bruceharrison1984

Description

Output from Angular-Typescript generator cannot be packaged/compiled because Authorization query parameter variable is not initialized.

    public getKeyResult(id: number, observe: any = 'body', reportProgress: boolean = false ): Observable<any> {
        if (id === null || id === undefined) {
            throw new Error('Required parameter id was null or undefined when calling getKeyResult.');
        }

        let headers = this.defaultHeaders;

        // authentication (apiKeyHeader) required
        if (this.configuration.apiKeys && this.configuration.apiKeys["Ocp-Apim-Subscription-Key"]) {
            headers = headers.set('Ocp-Apim-Subscription-Key', this.configuration.apiKeys["Ocp-Apim-Subscription-Key"]);
        }

        // authentication (apiKeyQuery) required
        if (this.configuration.apiKeys && this.configuration.apiKeys["subscription-key"]) {
            queryParameters = queryParameters.set('subscription-key', this.configuration.apiKeys["subscription-key"]);
            ^^^^^^^^^^^^^^^ error is here
        }
