Error when trying to add additional users to project sharing


If you are using the Project Sharing feature in RStudio Server Pro, you may experience errors when trying to add many users to a project - for instance:

RStudio was unable to share your project.
Could not apply execute ACL on {path/to/directory} system error 22 (Invalid argument)

If this occurs, it may be an issue with the file system you're using with RStudio Server Pro. A system like XFS, for instance, has a maximum of 25 ACL entries for a directory. Try moving the project to a different file system. 

Let us know if this solution doesn't work for you or if you're still seeing issues.
