PITR has errors "scan binlogs: sql: expected 2 destination arguments in Scan, not 3"

I’ve rolled out a new cluster, integrated Google bucket storage in S3 mode, done a manual backup without any issue, and am now trying to get PITR to S3 working, but I keep getting this error from the PITR pod:

2021/05/18 13:50:08 ERROR: get binlog time get binlog list for host lithium-pxc-0.lithium-pxc.percona.svc.cluster.local: scan binlogs: sql: expected 2 destination arguments in Scan, not 3

2021/05/18 13:50:08 ERROR: new db connection: get host: can’t find host

binary logging is definately enabled:

Cluster is ready and working, everything is in sync, just dont know whats going on here with PITR.

Thanks in advance,

I saw your message in discord. Seems you are running MySQL 5.7. PITR is supported in 8.0 for now as per About backups - Percona Operator for MySQL based on Percona XtraDB Cluster

Point-in-time recovery is off by default and is supported by the Operator only with Percona XtraDB Cluster versions starting from 8.0.21-12.1.

Hi @Sergey_Pronin 100% correct yes,

I will be upgrading my cluster shortly, just waiting to upgrade my database connection pools to Hikari in our java apps first.

Thanks for the response.
