Hello,
Although “unitless” is an alias of the dimensionless:unitless unit, try_get_unit(“unitless”) returns null.
ref: https://github.com/cognitedata/units-catalog/blob/main/versions/v1/units.json#L1699
Could you please have a look?
Thanks!
Question
try_get_unit udf cannot resolve dimensionless:unitless unit
Hi
There are currently two units from different quantities that possess the alias "unitless". When using the try_get_unit UDF, if the function encounters more than one unit, it returns null due to the ambiguity.
That being said, you can add "Dimensionless" or "Dimensionless Ratio" as a 2nd argument (quantity) to try_get_unit to circumvent the ambiguity, and that will return the associated unit, as the catalog enforces unique aliases within a quantity, but not across quantities.
