Error when exporting reports

Some users get the following error when trying to export reports:

uncaught Error in $A.getcallback() [Cannot read property 'getBoundingClientRect' of null] 

Any idea what might be causing this?

HI Matthew,
Based on the error I believe there is a custom lightning component involved  and a call like getElement().getBoundingClientRect() is made.

This error generally means you are trying to use a property on something that is null. Make sure you have an object to operate on before trying to use the property. I.e getBoundingClientRect expects a dom element.

You might need to loop in a member of the development team for reviewing the code to understand why specific users are affected.
