Greetings, I am observing a potential return of ticket 7012 in NiFi 1.15.3.
References: https://issues.apache.org/jira/browse/NIFI-7012 https://stackoverflow.com/questions/64750710/nifi-fails-to-start-after-setting-sensitive-parameter-into-non-sensitive-propert On initial startup of NiFi 1.15.3 on my project’s flow, NiFi fails to start due to the below stacktrace. This relates to a sensitive parameter context property for a sensitive field in a MongoDBControllerService. As a result, this appears to me as the same error as the referenced defect ticket above. I tried a couple different things to get past this error, including one from the stackoverflow reference above, but that caused unwanted problems. The most graceful technique I found was to string-replace my prior version of NiFi (1.13.2) with 1.15.3 within the raw flow XML for at least all the mongo processors’ MongoDBControllerServices, This relates to NiFi-packaged mongo processors and my project’s open-source mongo processors. However, in attempting this string-replace, I admit I may have also string-replaced additional items beyond the various MongoDBControllerServices that had 1.13.2 marked to achieve a successful start-up of NiFi and successful execution of all mongo processors at runtime. While this change did seem to work, I would like to confirm that it is necessary to do this work-around for successful start-up, or am I missing something?
