Hi Ivy team,

each time when starting Axon Ivy Designer an error box welcomes with the following content:

"An internal error occurred during: "Verify Web App Libraries". java.lang.NullPointerException".

The Designer works after closing the error message, so this is not a real problem. What is the reason for the cryptic message? Tested with Axon Ivy designer 6.7.1 Rev 55496 on Windows and Linux.


Eclipse error log shows:

eclipse.buildId=unknown java.version=1.8.0_144 java.vendor=Oracle Corporation BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en Command-line arguments: -os win32 -ws win32 -arch x86_64

An internal error occurred during: "Verify Web App Libraries".

In error log I see also two errors for starting BPM engine with ConnectivityDemos and QuickstartTutorial I made edits to.


Steps to reproduce:

  1. select a new workspace
  2. import all axonivy demo projects
  3. unpack connectivityDemos and edit some label.
  4. save close and restart designer

Full error log is here [1]

Best regards,

Hi Adam

The origin of this issue must be one of your projects in your workspace. Can you send us this project? Some more error details would be also great - StackTrace, ErrorLog etc.

Hi Alex, thanks just updated my post. I will try to remove the connectivityDemo and quickStartTutorial demo projects and import again.
