Do you see the same error string in nifi-app.log ? or there are any additional information in applogs ? if you see more details, please provide.

Are you able to make any changes to flow design ?

Can you please permissions and space is fine where flow.xml.gz is placed?

 

Thank You.

Hi @ckumar 

 

The flow changes made are not being saved in the Nifi. All read and write permissions are given to file flow.xml.gz.

I can see one error in nifi-app.log. "Error initializing the cipher". Below is the error. Is this causing the issue?
