Hi. I’m using Zoom Web SDK to jon a meeting.

Hey @JeffD, After looking into this we were unable to reproduce the error. Can you please share your code so we can debug and provide steps to reproduce the error? Thanks, Tommy ---

Hi Jeff, While we were troubleshooting, we weren’t able to see why screensharing wasn’t working, However, we used your credentials and meeting ID with a fresh install of our [sample web app](https://github.com/zoom/sample-app-web) 1.6.0 and it works(see screenshot below). Looking at the code it seems that developers are re-organizing the structure of the index.js file which is out of the scope of our support. Can you check with the developers and see if the screen share works when redownloading the WebSDK as is without re organizing the code base? ![39%20AM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/1/1e2af561cb8aa3d5c9aff8a440d02a7e74203773.png) ---

Hi @farooq.ahmed, Can you open the console log and see if any errors are showing up? Also, if you have deployed this on your dev server, make sure to use use `https` as it’s a requirement for browsers to allow access to your mic and camera. ---

Hi, I am getting this error while trying to screen share. ![Screenshot 2021-07-06 at 8.27.16 PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/9/d/9d6fc6c81b1812af2ef543a7d2e89010d226e0e4.png) Any Ideas why this might happen? ---

@mihai.temian yes. Solution: I found that `e.desktopSharingvalue.video` is expected to be `video` element but instead we receive `canvas`. You can search for this id: `sharer-client-sharing-canvas` in your sdk code and change the element from canvas to video. It should work. ---

Hey @madhurya and @mihai.temian, Thank you for reaching out to the Zoom Developer Forum. What version of the [Web SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/web#zoom-web-sdk) are you using when you see this? Was this working before or is this a new implementation? Thanks, Max ---
