But all is not lost for the Welsh side as they don't have to wait long for a shot at revenge as they welcome Saracens to the Liberty Stadium in less than a week's time.
And Johnson has called on fans and players alike to help put the disappointment of the loss firmly behind them and make it a night to remember in Wales.
"Disappointment is the dominant emotion I think," he said. "We're disappointed but the competition being what it is, it's probably the 'best worst' result we could have.
"There's a pretty quick turnaround now, we'll look at it and see we didn't do ourselves justice, but at the end of the day resolve got us a point and that's a quality that I like.
"You have to give credit to the opposition as well. To come up and just expect to win, I don't think that's paying due credit to the opposition, this is a tough tournament, we're in a tough group and they are a quality side.
"We're not going to take them lightly at home, playing there doesn't just give us a divine right to walk up there and win, we've got to make sure we do our job well. This is a quality side we're up against - and we're a quality side.
"We had a large following in the stadium and they made a big impression, that's for sure, and the guys appreciated it. It's just a shame at that end we couldn't quite give them what they wanted.
"Just as the players have to pick themselves up and go for it all over again on Friday night so do the fans and we'll need them to be with us all the way, making that kind of noise again and really showing their loyalty to the team.
"We're very proud to represent them and want them to be proud of us. The Liberty isn't an easy place for teams to come, but we've all got a big part to play if we are going to keep that unbeaten record going."
