Review Comment:
   As I see now this the same string as was used in `unexpectedFormatForSetConfigurationError`.
   I think we can introduce a `val` for it (in `QueryParsingErrors`) and reuse it.

Review Comment:
   This is definitely an improvement over the previous state but I think we can go a bit further:
   - The string interpolation is not needed as there is no outer val/var used inside.
   - I do not get why replaceAll was used in the first place but a simple string concat would do especially as there is no `"` within the content.
   
   So I would just simply:
   ```
   "Expected format is 'RESET' or 'RESET key'. If you want to include special characters " + 
   "in key, please use quotes, e.g., RESET `key`."
   ```
   So no `s"""`, no `stripMargin` and no `replaceAll("\n", " ")`
