SIFR-WORKSPACE-0003: Workspace source root is not a directory. - Sifr

SIFR-WORKSPACE-0003 belongs to the Workspace metadata diagnostic family. It means: workspace source root is not a directory.

Why It Happens

Workspace metadata does not describe a valid Sifr source layout. Keep source roots inside the workspace and use valid member/source-root shapes.

Use sifr --explain SIFR-WORKSPACE-0003 locally to see the renderer’s exact message template and any machine-applicable suggestions for the compiler version you are running.

Erroneous Code

[workspace]
members = [123]

How To Fix It

Fix workspace metadata so source roots stay inside the workspace and each entry has the expected string/path shape.

Fixed Code

[workspace]
members = ["crates/app"]
