command '{0}'

Error message

command '{0}'

What it means

Not a standalone error: it is the Display formatting for ArgumentSource::Command, rendering 'command '<name>''. It appears only as context inside larger error messages produced by the arguments resolution stage, identifying that the failing argument belongs to a command rather than a model.

Solutions

1. Read the rest of the error message: the actual failure is attached after 'command '...''
2. Fix the command's argument definition in its OpenDD YAML (usually the argumentType)
3. Rebuild and confirm the command resolves

// Handle the wrapping error; use the 'command '...'' name to jump to the command's OpenDD definition and fix its argumentType.

When it happens

Trigger: Surfaced when an argument defined on an OpenDD command has an issue (e.g. its boolean expression type fails to resolve) and the ArgumentSource is formatted into the error output.

Common situations: Command arguments whose argumentType references a broken boolean expression type; the prefix points you at the specific command in the metadata to fix.
