Thanks, @MichelDiz we were able to bulk-load the data by editing our rdf file. But after a successful load, we are still not able to see our data in the ratel. We checked our docker out and p directories are created.
We also tried doing a live load after this but we are getting context deadline exceeded. We tried both using localhost and docker network IP. Also when we imported data, we saw the schema file is empty.
PS: we are upgrading from v1.0.5 to v22.0.2
