McInnes suggested his side might have got away with one when he was asked about the decision to deny St Mirren going into a 3-1 lead in Paisley.
The VAR team deemed Mark O’Hara, who was in an offside position, interfered with play by blocking the path of Lawrence Shankland when Hearts were attempting to defend a deep free-kick.
The move ended with Miguel Freckleton escaping Hearts’ high line and scoring what he felt was a third St Mirren goal, but referee Matthew MacDermid agreed with the VAR when he reached the monitor.
That set-play was one of many that caused carnage in the Hearts box, something McInnes referred to post-match.
But the Hearts boss was equally as keen to reference the resilient mentality that ensured his side left Paisley with a point, extending their 10-game unbeaten start.
“We’re disappointed with the goals we lose,” McInnes added. “It’s the first time we’ve looked susceptible from set-plays.
“Sometimes St Mirren put that pressure on you and you make poor decisions. But by and large I thought we were good in the game.
“I loved the way the team were at the end. The support stay there at the death because they feel another goal is coming.
“That’s a great feeling to have as a manager, you feel the players are doing everything to get that winning goal.”
