Research direction
Reproduce the issue in Apache Hop 2.9 on Java 11 using a new pipeline with a Data Grid step feeding a JSON Input step. Run it with HOP_EMPTY_STRING_DIFFERS_FROM_NULL unset and then set to Y, restarting Hop GUI between runs. Done means the JSON Input step output distinguishes an empty string from null.
