Hi @j_a_z_z and @tmiskiew,

Based on the information in your [other post](https://devforum.zoom.us/t/how-to-manipulate-the-floating-panel/38747), I suspect that this is due to there not being an active screen share when calling these methods. Please let me know if you see the error for any of these while a screen is being shared and we can look into this further.

Thanks!
