20 : Error
Message
(<insert_1>, <insert_2>) : <insert_3> is not boolean.
Explanation
A search condition evaluated to <insert_3>, which is not a boolean value. Search conditions must evaluate to boolean values.
Response
Correct the syntax of your ESQL expression in node <insert_1>, around line and column <insert_2>, then redeploy the message flow: Ensure that the search condition evaluates to a boolean.
