I have just setup the snowplow enrich process using R97 Knossos.
The process completes successfully, but the enrich/good folder contains no folders, and just empty files with the name pattern
run=[timestamp]_$folder$
In enrich/bad I can see matching folders, with two files (_SUCCESS and part-....-.txt).
In archive/enrich I can see a matching folder with the same ifle pattern as above, but also an empty file with the run name and _$folder$ appended.
I’ve noticed there has been a similar issue which should now be fixed here: https://github.com/snowplow/snowplow/issues/3139
