When I try to update to Beta 1, I get this huge error: https://pastebin.com/0URUjGai Any ideas?

I was getting that too and updating other dependencies fixed it. I believe updating to

androidx.activity:activity-compose:1.3.0-alpha03

in particular fixed it for me.

Thanks but I've already updated it. 🤔

Not that I remember. I upgraded that lib along with

androidx.lifecycle:lifecycle-viewmodel-compose:1.0.0-alpha02

and

dev.chrisbanes.accompanist:accompanist-coil:0.6.0

. After that, the error went away.

aha, thanks for this, it was the viewModel one which I had forgotten to update. Phew! 🙏
