We also ran into this issue doing .map() on an array. Our issue was not very reproducible, only occurring a handful of times a day out of many users. Replacing the .map() call with a basic for loop seemed to avoid the bug (or it's failing in a way that doesn't show up in our logs anymore). I couldn't find any common threads outside of the users all being in a webkit browser (safari on mac or any browser on iOS/iPad). The arrays that caused this error were sourced from multiple different code paths. Thanks!
