I suggest you track back which commodities you have recently downloaded. Make a list of those, delete a bunch of them, restart the route and see if you still get the error.
Is it no longer there? Re-download a few.
Is it still there? Delete a few more.
Keep doing so till you have found the commodity that results in this error... and then share the name and KUID so we can figure out what is wrong with it.
Or at least this is what I would do. Happy to read alternative solutions.
