@Runa27  I don't have a windows system at the moment, but I downloaded Apache NiFi 2.7.2 and openJDK 21 on a small Centos 9 VM.  Unzipped and started it.  So default using the single-user authentication and authorizer.  JDK 21 is the required java version for Apache NiFi 2. Once i accessed the UI, I added a GenerateFlowFile processor and connected it to a UpdateAttribute processor.  Configured GenerateFlowFile processor to create a 10 byte file. I was able to list the success queue and view the content of the flowFile.  What Java version are you using? What Windows version are you using? What browser are you using?  Did you try a different browser ( I am using Chrome)? When you try "view content", it should open a new browser tab where it would load the content viewer.  I assume this new tab is being opened where you then see the exception? Try opening the "developer-tools" available in your browser.  Then try to refresh the tab and you see the requests and response made.  Somewhere in that you should see your exception being thrown as a response. That info may give more insight into what your issue is loading the content viwer. Please help our community grow.

I am new to Nifi and trying to load csv data in postgres but I am getting error: FlowFile[filename=test_data.csv]. Routing to failure.: java.lang.IllegalArgumentException: Record does not have a value for the Required column 'name' so I have checked everything and the csv file I am uploading contains the data. I have also checked solutions for issues like this but nothing worked out. I will attach liks to the screenshots it contains the configuration for PutDatabaseRecord and the query for the table I created in postgre and screenshot of the csv file.  https://drive.google.com/file/d/1TCJTcNJHRslG4wEct1eZmuYz54Gp9e9o/view?usp=drive_link https://drive.google.com/file/d/1Ye6pggRN4YTQVGxylNarjZh4dlX-ByQ1/view?usp=drive_link https://drive.google.com/file/d/17zLRe88DSssU9DI3rrJLCHQmUgAj9FYX/view?usp=drive_link https://drive.google.com/file/d/1XKt1jbZks8jE0kO4CrT3nmRR4LFcIn1e/view?usp=drive_link   Note: please let me know how I can upload image here directly ...

@Runa27  management.server.address -- defines HTTP URL on which NiFi listens for management requests. Doc Ref : https://nifi.apache.org/nifi-docs/administration-guide.html Please try setting below property as part of " bootstrap.conf " and then start the Nifi service. java.arg.mng12=-Dorg.apache.nifi.management.server.address=127.0.0.1:<port-number> Please check if the port-number <for example: 9990> is not defined and replace the same in the property  Please help our community grow.
