Hello everyone, having a problem accessing Jupyterhub.  
I was getting Unhandled errors while navigating jupyterhub. I tried respawning my server and I keep getting this error in the server options screen. Any thoughts?

Thanks

(Edit: RStudio works normally, error is only on jupyterhub  
Edit2: RStudio cannot save changes in scripts - doesnt detect the file)

_Error: HTTP 500: Internal Server Error (Error in Authenticator.pre\_spawn\_start: RuntimeError sbatch: error: Batch job submission failed: I/O error writing script/environment to file)_

Tried saving a script but got an error, I try to respawn server and get locked out:

_Error: HTTP 500: Internal Server Error (Error in Authenticator.pre\_spawn\_start: RuntimeError sbatch: error: Batch job submission failed: I/O error writing script/environment to file)_

Thank you for your efforts,
