Error: Multiple files resolve to the same underlying canonical file


You’re unable to sync your domino project and receive the error message:

You have multiple files in your project that resolve to the same underlying canonical file (see the list below). This is probably because you have a symlink pointing to another file also in your project, or multiple symlinks pointing to the same file.


Some common things that can cause this error to pop up are:

  • Installing a program that uses symlinks (e.g., Juli) into your project directory.
  • When using the CLI, running “domino sync” from within the wrong directory (e.g., from your home directory, instead of the Domino project directory).


Installing programs inside a project directory is not recommended in favor of installing them in your compute environment. By taking advantage of Domino’s compute environments, you can install your programs at the system-level, use the program in other projects, and reduce project bloat.

If you're running “domino sync” from the CLI, ensure you’re running it from the correct directory - depending on the structure of your project, that will either take the form of [projectname] or [username]/[projectname].
