Cargo include must be a string, array, or table in

Error message

Cargo include must be a string, array, or table in {}

What it means

Type-dispatch fallback in cargo_config_includes: the Cargo include item in the config file is not a string, not an array, and not a table — the three supported shapes. Reached when e.g. an include is declared as an integer or boolean. The error names the offending config file so the user can fix the TOML type.

Solutions

1. Add `path = "other-config.toml"` to the include table
2. Or use the plain string include form
3. Fix the config file syntax and retry
