					"body": "*Wait*. This may be unrelated to the Ti.Database code. I bet it is related to the \"Bluebird\" library used to handle promises that relate to the database operations. I'm pretty sure other async operations would trigger the same issue. Also, that guess is hardened by the fact that the error occurs while require'ing a CommonJS module, which..well..\"app/lib/bluebird.js\" is. I also remember that we had issue with the Bluebird library before. Is this still needed these days with us supporting ES6+?\r\n\r\nPlease see ALOY-1604 which is about a related issue with Bluebird incl. a way around the error. I assume iOS 12 adds some ES6 API's built-ins (like some {{Promise}} specs), which overlap with the ones provided by Bluebird.\r\n\r\nNot wanting to drag you into this [~eharris], but you have stated good points on the other discussion and will likely have more insight here. In the meantime, I will find out what part of the library causes it.\r\n\r\n*EDIT*: Besides that, testing with 7.4.0.v20180828081144, it does not crash. Let's wait for the reporter and some more details. Removing 7.4.0 milestone again for now.",
