Just to inform …
I use Knime 5.1.1 and try to write some data in the Neo4j database with the Neo4j Writer Node but I get the error “ERROR Neo4j Writer Execute failed: javax/json/Json”
If I run the same workflow with KNIME 4.7.1 the Neo4j Writer Node executes without errors and the data is in the database.
In both the 4.7.1 and 5.1.1. KNIME version the Neo4j extension version is 1.0.1.v202207061143
In both versions of KNIME the Neo4j Connection Mode connects to the database without errors
