https://community.cloudera.com/t5/Support-Questions/NiFi-Need-to-help-to-merging-combine-join-2-Json-FlowFile/m-p/370187#M240641 <P>I can confirm that there is behavior change in Fork\Join Enrichment processors between 1.16 and 1.20. I have uploaded the same template you sent using 1.16 and it worked using 1.16 JsonTreeReader\Writer , however the same template did not work on 1.20 using 1.20 processors and services. <a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/35454">@MattWho</a>,&nbsp;<a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/95503">@steven-matison</a>&nbsp; Is this a bug or misunderstanding if how such processors and services should work in the later versions? Please advise. Thanks</P> Sat, 06 May 2023 16:06:40 GMT SAMSAL 2023-05-06T16:06:40Z
