BIP2925
Severity
20 : Error
Message
(<insert_1>, <insert_2>) : A byte array literal must have an even number of digits.
Explanation
This is most likely to have been caused by attempting to use a X' literal with an odd number of digits (0-9, A-F, a-f) between the quotes.
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 literal has an even number of digits.
