KeyError if target data have invalid values

[babetsdasha]

Hi, everyone. IDataProviderTarget have optional parameter intensity_metric, but if target_type="int" and target doesn't have intensity_metric, we are getting an error (in case that we have only 1 target)

KeyError: "None of ['company_id', 'time_frame', 'scope'] are in the columns"

here
https://github.com/OFBDABV/SBTi/blob/master/SBTi/target_validation.py#L40

I have a few suggestions how it can be fixed

• extend IDataProviderTarget validation
• put default value for intensity_metric

Here is test for reproduce the issue

        # here exception
        portfolio_data = SBTi.utils.get_data([data_provider], [pf_company])

        scores = temp_score.calculate(portfolio_data)
        self.assertIsNotNone(scores)
        self.assertEqual(len(scores.index), 3)
