Debug adapter schema for `{debug_adapter_name}`(path: `{debu

Error message

Debug adapter schema for `{debug_adapter_name}`(path: `{debug_adapter_schema_path:?}`) is not a valid JSON

What it means

The debug adapter schema file for {debug_adapter_name} was loaded but is not valid JSON — serde_json failed to parse its contents. Distinguish from the read error: the file exists and is readable, but its content cannot be parsed as a JSON schema; the adapter cannot be registered without a parseable schema.
