ERROR: Invalid settings.palette.nodesExcludes When trying to enable persistent file storage node in docker

### Current Behavior

Running docker instance of flowforge by following the procedure outlined here -
https://github.com/flowforge/flowforge/blob/main/docs/install/docker/README.md

I have it up and running successfully and I can deploy instances no problem.

I had my flowforge instance updated from a community license to an enterprise license, and I wanted access to the flowforge specific nodes, one of those being the persistent storage node. So I followed the steps in handbook here -
https://flowforge.com/docs/user/filenodes/#enabling-persistent-file-storage
I modified the default template to allow the ability to exclude nodes by filename so I could exclude `10-file-js` as described in the handbook.

### Expected Behavior

When checking the box I shouldn't get an error, and I should have access to the flowforge persistent file storage node.

### Steps To Reproduce

I suspended the instance, went to the instance pallet settings and added `10-file-js` to "exclude nodes by filename.
I got this message

Here is the stacktrace of the error provided by the docker container log -
