Workflow runs from end to end on the Knime Analytics Platform and used to run without error on the server. Recently however have been getting the below error at the SharePoint Online Connector node which stops the workflow from being executed. Workflow continues to run fine on the local desktop.
ERROR SharePoint Online Connector 5:208:154: Execute failed: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
The errors seems to be related trust store, Did we change anything recently on your KNIME Server environment related to trust store or certificates? can you check if KNIME Server is pointing to the right trust store and the password is correctly configured?
Thanks Nagarjun for your insights.
Confirming that we did have an upgrade in server versions recently and the issue likely occurred around that time. After your above comment I begun comparing our backup server folder and noticed that the keystore.jks file hadn’t been copied into the new server folder.
After restarting the VM the workflows are back to working as expected. Once again appreciate your assistance with pointing me in the right direction.
