Issue with code not running after using args.rest('string') (NOT SAPPHIRE ISSUE)

    public async messageLink(message: Message, args: Args) {
        let region = 'na';
        let summoner_name;

        console.log('Message Content: ' + message.content);

        if (message.content.split(' ').length > 2) {
            const regionText = await args.pick('string');

            console.log('Region Text: ' + regionText);
            if (RiotUtil.isRegion(regionText)) {
                region = regionText;
            } else {
                summoner_name = regionText;
            }
        }

        console.log('Region 1: ' + region);
        console.log('Summoner Name 1: ' + summoner_name);


        if(summoner_name) {
            console.log('region was not specified, combining all args');
            summoner_name = summoner_name + await args.rest('string');
            console.log('Summoner Name 1.5: ' + summoner_name);
        } else {
            console.log('region was specified, setting summoner name');
            summoner_name = await args.rest('string');
        }

        console.log('Region 2: ' + region);
        console.log('Summoner Name 2: ' + summoner_name);
    }
