Getting "Uncaught (in promise)" while handling onBeforeExit event

[kambadprashant]

I have used the below code from the documentation: https://tourguidejs.com/docs/events.html#onbeforeexit

tg.onBeforeExit(()=>{ return new Promise((resolve, reject) => { if (confirm('Are you sure you want to close the tour?')) { return resolve(true) } else { return reject('User Cancelled Tour') } }) })

But it throws Uncaught (in promise) User Cancelled Tour
After that all buttons become unresponsive and console logs the following error Uncaught (in promise) Promise waiting

Have already updated the library to latest version (0.0.26)

Do i need to handle this error somewhere? Thanks in advance!
