Improve Indigo error reporting

**Background**
There are multiple reports about inconsistent Indigo error messages.
Here is a typical example:

https://github.com/epam/Indigo/issues/2045

**Solution**
Indigo reporting code should be structured and refactored.
Error messages' texts should be rewritten if they are unclear or don't reflect the essence of the error.

Start by reading the linked example issue 2045 and identifying the Indigo reporting code involved in its inconsistent messages. The issue provides no files, entry points, or tests; completion would require a structured reporting refactor and clearer messages that accurately describe each error.
