Hi all, Fairly new to Nifi, have read bunch of blogs/forums but was not still able to figure my issues out, so asking my questions here. Running Nifi 1.8.0 in a Docker Container, and trying to read from an Oracle DB and write to an Oracle DB (11g). Here is my target table definition : create table nifi_dim_bb_language ( pk integer, isocode varchar2(10), activeflag integer ); I've built 2 different dataflows and both are failing : A/ 1.QueryDatabaseTable > 2.ConvertAvroToJson > 3.ConvertJsonToSQL > 4.PutSQL Find enclosed the screenshots from every processor : 1.QueryDatabaseTable : I'm able to read the data from the source Oracle table (that only contains 3 records) properly and write them to a JSON file somewhere in a temp directory, here what's the JSON file looks like. {"PK": "8796093087776", "ISOCODE": "fr", "ACTIVEFLAG": "1"} {"PK": "8796093055008", "ISOCODE": "en", "ACTIVEFLAG": "1"} {"PK": "8796256927776", "ISOCODE": "de", "ACTIVEFLAG": "1"} 2.

Error : None of the fields in the JSON map to the columns defined by the nifi_dim_bb_language table 4. PutSQL : Nothing gets written into the table. B/ 1.QueryDatabaseTable > 5. PutDatabaseRecord 1. QueryDatabaseTable : Same processor as above 5. PutDatabaseRecord : I defined an AvroReader, and Insert as 'Statement Type' but still not working.
