Data that is imported from external websites need to be from secure endpoint. When an import activity from an external website fails it is good to run this activity in debug mode and check hte additional Debug logging.

It can happen that you see a PKIC error.

02-04-2025 14:34:26 DEBUG - PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested targetPKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested targetPKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

PKIX errors are typically related to certificates that are used when authenticating with an endpoint. This issue happens when your local computer attempts to connect to the cloud and the security certificates in your local computer keystore do not match. You will have to add the certificate of the website to a local client keystore file "client.truststore".  The following steps guide you in making such a local "client.truststore" file from the website that you use to import data from. Make sure the website is secure!

Google Chrome

  1. Right-click the page and select Inspect.
  2. Select the Security tab. Tip: If this tab is not visible, select the >> for a drop-down menu.
  3. Select View Certificate.
  4. In the window that opens, select the Details tab.
  5. Select Export to file. You will be prompted to select an export format. Export to a file $$$.cer

Delft-FEWS Stand Alone

  1. Open your Delft-FEWS Stand Alone application
  2. Press F12 to open the debug menu
  3. Select > Convert > Convert Certificate to client truststore file
  4. Select the $$$.cert that you stored
  5. Delft-FEWS will make a client.truststore file in the Region home folder

Once the client.trsutstore file is created, restart your Delft-FEWS Stand alone and check if you can import the data again. If you succeeded, make sure the client.truststore file is also copied to your Forecasting Shell Servers.
