pulumi: err: panic: runtime error: invalid memory address or nil pointer dereference

I’m experiencing this error on all of my pulumi python apps when running pulumi up. My code hasn’t changed and this error is popping up on all my projects. It creates the GKE cluster and 3 nodes but bombs out after that with the panic error shown below.

Pulumi v0.17.21 Operating systems tested: OSX and Linux
