This is happening only when the record doesn’t have a folder created but once the folder gets created the message will be gone this is very inconvenience for the users, is there a way to prevent it from showing up also, this is only happening with content explorer component
Hello Again! 
I’m not sure on this error! It looks like you already made a support request for this. They should be able to get you the help you need. Like I mentioned in my other post, they should be able to login to your Salesforce environment and track the errors.
Thanks,
Alex, Box Developer Advocate
