unknown: no variable or entity of that name. secret-not-allowed: the name is a project secret and this field does not accept one. path-on-non-variable: only a variable has fields. resource-id: a bare resource id, not a name. invalid-name: outside the ^\w{1,64}$ name grammar. dangling: the reference rendered as a bare id, because its row is gone or its name is outside the name grammar.
