I'm trying to insert or update table based on a unique key. But PutDatabaseRecord processor is throwing error: source for a multiple-column UPDATE item must be a sub-SELECT or ROW() expression
However no error is thrown with multiple columns. This error is only with one column
Simple User table with id(PK) and name columns.
Here is my PutDatabaseRecord config:

Here is my JSONTreereader: JSONTreereader config image
Please help me with this issue
