Hello everyone, I’m migrating from Twilio to Zoom and I’m having trouble getting a participant into the room. When it enters, the ‘peer-video-state-change’ event correctly detects the entry and obtains the userId correctly, however I get an error ‘zoom-video-1.9.8.min.js:1 Uncaught TypeError: zoomSession.attachVideo is not a function’. I have followed the migration instructions but I get that error. Also, if I get information from the payload, it comes out as action ‘stop’ when I suppose it should be ‘start’. Thank you all. ---

Hey @d.munoz.semesur , The `attachVideo` was introduced in version 1.10.7. If you upgrade your Video SDK version to `1.10.7` it will work. > **[Video SDK - web - 1.10.7](https://developers.zoom.us/changelog/video-sdk/web/1.10.7/)** > > The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform. Best, Tommy
