SCI embodied ambiguous error message

[MariamKhalatova]

Description of the Error

After receiving following error:

MissingInputDataError: `functional-unit` value is missing from input data or
    it is not a positive integer

as a user, I'm entering positive integer which results with another error:

InputValidationError:   "functional-unit" parameter is expected string, received number. Error code: invalid_type.

Expected Behaviour

First error message should guide what to fix.

Actual Behaviour

Misleading error.
