Data results below visualisation appear as 'undefined' when field name contains a dot.

Expected results

When there is no dot in field name, data results below visualisation contain values from dataset, as is expected.

Actual results

However, when field name contains a dot (field.name for example), values from this field appear as undefined in data results.
Note that it seems to be the case only in data results shown below visualisation, the request in SQL Lab or the actual visualisation are not affected and return the expected values.

How to reproduce the bug

1. Create a dataset with a . in one field name, on TimeScale DB
2. Create any chart using that field
3. Look at Data Results below chart
