BIP2578
Severity
20 : Error
Message
(<insert_1>, <insert_2>) : Dynamic field reference <insert_3> is not detached and therefore cannot be attached to <insert_4>.
Explanation
The message tree fragment pointed to by the dynamic field reference <insert_3> 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_1>, around line and column <insert_2>, then redeploy the message flow: Ensure that you detach the message tree fragment before attempting to reattach it elsewhere.
