Why i have this two errors when i use babylonjs

I am currently developing an application that displays 360° images and I use the BabylonJS library for that. And if today I come to you it’s because I have 2 errors that I don’t understand where they can come from
enter image description here
the first is: [.WebGL-00000A18072FEA00] GL_INVALID_OPERATION: Must have element array buffer bound.

and the second is :WebGL: INVALID_OPERATION: uniformMatrix4fv: location is not from current program
