Receiving "Config for key 'filter_mode' not found" error on Server and not on Local

Hello, we’re seeing the following error when running a workflow on the server that we are not seeing in our local development.

Here is the server error from the attached workflow which isolates the few nodes that are interacting to cause the error at the Create Temp Folder node

Workflows <>: Could not load workflow <server-path>: Errors loading workflow 'Temp folder test': Status: Error: Temp folder test 3 loaded with errors
  Status: Error: Temp folder test 3
    Status: Error: Create Temp Folder 3:332
      Status: Error: Loading model settings failed: Config for key "filter_mode" not found.

In the proper workflow, the error message is slightly different. The nodes are still similar enough, where a table-row-to-variable node is ahead of the create temp folder node:

There are messages for workflow "workflow_name"
  Create Temp Folder 0:332 - WARNING: Errors loading flow variables 
  into node : Config for key "filter_mode" not found.

I’ve tried to inspect the flow variables and I don’t see a “filter_mode” value in any of the configuration dialogues for either of the nodes.

I hope someone can help. Thanks in advance!

Posting here in case anyone else runs into this. The reason was a KNIME version discrepancy. The workflow was created on KNIME analytics platform version 4.4 and the executor is still on 4.3.

Reverting to use 4.3 locally and re-create the Create Temp Folder node fixed the issue.
