Hi,

Please check any project module .js file opened in any text editor, if so close it. Or this could be problem with the npm/node, restarting the Kony Visualizer will kill the background process and restart with fresh instance.

We need complete logs file to get more details on it, please share us the vizdata logs.

is restart is the best practice or any other suggestion?

Hi,

Based on the given logs, Visualizer is trying to release or unlink the file which is getting failed.

EPERM: operation not permitted, unlink 'D:\Users\451794\KonyVizEWS\.webapps\dcpApp\codegen1521446443470\android\src\require\com\rhbgroup\dcp\core\ApplicationButton\userApplicationButtonController.js'

Use Process-Explorer tool which will give us information which process has holding the file.

https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

We need to kill that process to complete the action.

How can i use the Process-Explorer tool?

i had downloaded it just now.

Hi,

Open Process Explorer, running as administrator.
On the toolbar, find the gunsight icon on the right
Drag the icon and drop it on the open file or folder that is locked.
The executable that is using the file will be highlighted in the Process Explorer main display list.

1) for open file/file is locked.. do u mean project file? or any file?

anon-4 · March 20, 2018, 11:13pm

Hello,

You need to open the file "D:\Users\451794\KonyVizEWS\.webapps\dcpApp\codegen1521446443470\android\src\require\com\rhbgroup\dcp\core\ApplicationButton\userApplicationButtonController.js" to check any process holding lock on it.

is it because node.exe running background?

anon-4 · March 21, 2018, 7:28pm

Hi,

Thank you for the update, can you please share us the screenshot of the process-Explorer with requested file. Also what you can do is, open the D:\Users\451794\KonyVizEWS\.webapps and delete the dcpApp folder before you open the application.

Let us know the manual delete is allowing or not. If possible please share us your project to verify the problem with Visualizer or application code.
