BIP2578
Severity
20 : ErrorMessage
(<insert_0>, <insert_1>) : Dynamic field reference '<insert_2>' is not detached and therefore cannot be attached to '<insert_3>'.Explanation
The message tree fragment pointed to by the dynamic field reference '<insert_2>' has not been detached. Only message tree fragments which are detached can be attached to another message tree.Response
Correct the syntax of your ESQL expression in node '<insert_0>', around line and column '<insert_1>', then redeploy the message flow: Ensure that you detach the message tree fragment before attempting to reattach it elsewhere.
