whale broswer Class constructor f cannot be invoked without

[joonsu1229]

Hello.
I'm using naver whale broswer.
The error does not occur in Rocket.Chat version 6, but it occurs in version 7.x


Chrome and Edge work fine, but as soon as I enter Rocket.Chat in Whale browser, a script error occurs. How can I fix this
Uncaught TypeError: Class constructor f cannot be invoked without 'new'
Please tell me how to fix this error.

An error occurs at class RestApiClient extends RestClient in RestApiClient.ts, as shown in the image below.
