TypeError: Cannot read properties of undefined (reading 'isProxied')

[rkang30]

Describe the bug
When it's built via npm run build, it's showing me this error (TypeError: Cannot read properties of undefined (reading 'isProxied')) in my console on chrome browser.

And the date picker is not showing up at all. I notice that the html element 'duet-date-picker' did not add class="hydrated"

(fyi, it's working fine on my local - in other words, before 'npm run build')

To Reproduce
Steps to reproduce the behavior:

1. npm run build
2. upload it to server
3. check it out on the chrome browser
