Hello everyone, My NIFI pipeline gets data from DB2 using QuaryDatabaseTable processor. When I launch it get exception (org.apache.nifi.processor.exception.ProcessException: Error during database query or conversation of record. I found out that the problem with some char in a table's field. I see this in the nifi log (nifi-app.log) and I see there that it falls with an exception java.nio.charset.UnmappableCharsetException: Input length = 1. What I tried. I used another JDBC connection driver. I tried to set UTF8 in bootstrap.conf and nifi-env.sh (I found this tip here). It has not helped. Could you help me, please?
