Unable to get location of camera for scrolling

Hi folks, need your help please, i’m trying to get the camera actor of my scene location but le blueprint is ok,

but i have this error on the log

Blueprint Runtime Error : “accessed None Trying to read property camera” Blueprint : Main, node set actor location

And the scrolling don’t work, i’ve tried almost all possibility, i’m saw some tutorial where camera actor work

here is the bp its the evengraph of the blueprint level

yes the blueprint work, but i’ve another issue, i will post a new thread thanks a lot, i will close this one,

I think this BP works, but the error is from when you were using the camera component ( on the left )?
