(Oracle) Data Pump compatibility?

Question

I'm currently experimenting van different versions of Data Pump. (Oracle) We have a bunch of dev oracle servers at work. Versions 11, 12, 18 and 19.

If I recall correctly, Oracle 19 should be backwards compatible with 18, 12 and 11. I can successfully connect to the Oracle 12 server using the Oracle 19 client, but when I try to do a export using Datapump I get the following error:

Any ideas? Shouldn't Data Pump also be backwards compatible?

Thanks in advance.

Generally speaking, you should

• export data using the lowest data pump export utility version involved (12c in your case)
• import data using the target database version's data pump import utility
