'NiFi doesn't start on MacOS Big Sur

I have installed NiFi using Homebrew following the instructions on this page.

Once I go start NiFi using

nifi start

I get the following:

Java home: /usr/local/opt/openjdk@11/libexec/openjdk.jdk/Contents/Home
NiFi home: /usr/local/Cellar/nifi/1.15.0/libexec

Bootstrap Config File: /usr/local/Cellar/nifi/1.15.0/libexec/conf/bootstrap.conf

Error: Could not find or load main class org.apache.nifi.bootstrap.RunNiFi
Caused by: java.lang.ClassNotFoundException: org.apache.nifi.bootstrap.RunNiFi

I also see this error in the nifi-app.log

Any ideas?

Solution 1:[1]

I got the same error. Mine was due to the 8443 being occupied. I think, you can either find what's using the 8443 or you can try to change the port nifi.web.https.port=8443 in ./bin/conf/nifi.properties to something else. I hope it helps if you are still facing the issues.
