failed to read debug adapter schema for `{debug_adapter_name

Error message

failed to read debug adapter schema for `{debug_adapter_name}` from `{debug_adapter_schema_path:?}`

What it means

While testing an extension's debug adapters, loading the adapter's JSON schema file failed at the FS layer. The schema path is derived from the manifest's debug_adapters entry; the load failed because the file is missing, unreadable, or a broken symlink at {debug_adapter_schema_path}.

Solutions

1. Ensure the schema file exists at the path derived from the manifest entry (typically debug_adapters/<name>.json)
2. Fix the path declared in extension.toml's [debug_adapters] section to point at the actual schema file
