SendBird.min.js:3519 Uncaught TypeError: l.isMatchingType is not a function

Facing l.isMatchingType issue while integrating sendbird with my react app.

I am using,

  1. “react”: “^16.13.1”,
  2. “react-dom”: “^16.13.1”,
  3. “sendbird-uikit”: “^2.2.1”,

However, after trying to do a POC with the above config, I am not facing any issue. So, just wanted to know where should I look for this issue.

This issue is resolved. We have added a extension method to Array.prototype which was causing this issue.

However, its an important extension so It would be great if sendbird provides an out of the box solution for this issue.


Welcome to the Sendbird Community. Extending the array prototype has been known to cause issues in the past with the JS SDK. This is something we are aware of and currently discussing internally.
