V1.12-beta5 SITL Gazebo "Preflight Fail: Accel 2 uncalibrated"

I am trying to run SITL iris out-of-the-box but it can’t takeoff because of a pre-arm check failure.
It keeps giving the error “Preflight Fail: Accel 2 uncalibrated”

I tried it on the Master branch and on v1.12-beta5
Before running make px4_sitl gazebo_iris I also ran
git submodule update --init --recursive
to ensure the submodules, like Tools/sitl_gazebo, are on the correct commit.

Any suggestions on what the issue is and how to fix this?
Is it a firmware issue or is there something different on my machine?
