"Missing version string in comparison" error

Hi all

I’m testing and crashing a node on purpose, so SST is initiated. And get this error on the joining/crashed node on startup. Everything completes and node is sync’ed.

“left-side: operation:< right-side:2.4.29” seems to be the problem.

I’m using the Docker image percona/percona-xtradb-cluster:8.0 for PXC.

I guess 2.4.29 (XtraBackup) is not possible to retrieve inside the Docker container.

Can I ignore this error or can it be fixed?
