The importmulti help text reads, in part: 

```
{                                                          (json object) If a ranged descriptor is used, this specifies the start and end of the range to import
           "start": n,                                              (numeric, optional, default=0) Start of the range to import
           "end": n,                                                (numeric, required) End of the range to import (inclusive)
},
```

This is a value for which a key is missing; it should be "range": { ...
PushSection({indent + "{", right});
            for (const auto& arg_inner : arg.m_inner) {
                Push(arg_inner, current_indent + 2, OuterType::OBJ);
            }
            if (arg.m_type != RPCArg::Type::OBJ) {
                PushSection({indent_next + "...", ""});
            }
            PushSection({indent + "}" + (outer_type != OuterType::NAMED_ARG ? "," : ""), ""});
            break;
        }
        case RPCArg::Type::ARR: {
            auto left = indent;
            left += outer_type == OuterType::OBJ ? "\"" + arg.m_name + "\": " : "";
            left += "[";
            const auto right = outer_type == OuterType::NAMED_ARG ? "" : arg.ToDescriptionString();
            PushSection({left, right});
            for (const auto& arg_inner : arg.m_inner) {
                Push(arg_inner, current_indent + 2, OuterType::ARR);
            }

            break;
