# No Single File Deployments #### Why This Error Occurred You attempted to create a Vercel deployment where the input is a file, rather than a directory. Previously this was allowed, however this behavior has been removed as of Vercel CLI v24.0.0 because it exposed a potential security risk if the user accidentally created a deployment from a sensitive file. #### Possible Ways to Fix It - Run the `vercel deploy` command against a directory, instead of a file.
