Hi,

 

In a production site, running 9.13.8, in Monitor Event Viewer we get the following report:

  • LogAction: Unhandled
  • LogDescription: Parameter is not valid.
  • LogUsername: System
  • LogDate: 2024-05-10 13:23:17.280
  • LogFilePath: /EventViewer/2a14d4bd-8efb-48e9-a0f2-4df55eacff53
  • Url: /Admin/Public/GetImage.ashx?Width=1920&Height=845&Crop=0&DoNotUpscale=True&FillCanvas=False&Image=%2fFiles%2fFiles%2fDW-DEMO_2020-11-09_175815-DefaultEndpoint.zip&AlternativeImage=%2fFiles%2fImages%2fmissing_image.jpg

 

Getting to the log file itself doesn't provide me with a lot of info either

2024-05-10 13:23:17.279: Parameter is not valid..

I'm trying to find anything that points me to where this is happening OR if it's fixed in a newer version:

  • I've checked Bug Fixes for 9.13 and above for terms related to "Image" and "Monitoring"
  • I've looked into EcomProducts and EcomDetails tables that could be wrongly referencing that Zip file (although very unlikely) - no results
  • If I were to guess it would be from backend users having a thumbnail view of files in the backend - but I can't be sure
    It keeps happening/getting reported in Event Viewer

 

Does anyone have any clue or information on what my next steps could be?


Best Regards,

Nuno Aguiar

Could be a spam request. Could be someone who selected a zip file for an image.

Later versions will show the URL called that caused this.

Hi Nicolai,

 

Thank you. At least knowing newer versions have more for me to go on is helpful.

 

Best Regards,
