Hi this is a issue related to kotlin version update, we are working on the fix and will update you as soon as this is resolved meanwhile you can fix it by replacing all occurrence in cometchatplugin.kt:

result.error(e.code!, e.message, e.details) with result.error(e.code!!, e.message, e.details)

Sorry for the inconvenience
