We have detected an error in our code that occurred while reading in spin independent (SI) Xenon1T constraints. This bug affects the spin independent constraints and decreases the constraint on the dark matter coupling gDM by an order of magnitude in some regions of parameter space. This does not affect our conclusions in the paper that the spin independent constraints are dominant for large dark matter mass, nor does it affect the general pattern of these constraints, namely, that they are strong when the mass of dark matter and mediator are not too different. However, the exact region of parameter space where SI constraints dominate collider and spin dependent constraints changes and as a result, as do the numerical values of gDM on our figures. Figures 1, 2 and 3 are the updated plots corresponding to figure 6, figure 13 and figure 14 respectively of ref. [1]. In figure 2, we see that SI constraints dominate for large dark matter mass, collider constraints become important for intermediate and small dark matter mass and spin dependent constraints are relevant only for very small dark matter mass.
