Hi,

I'm trying to query the FieldDefinition object to get the technical details of a field for creating a mapping file. If I query the "Description" field, the query runs without error, but the "Description" column doesn't return any values. While in setup, I can clearly see descriptions are filled in for those fields.

Example query: 
SELECT DeveloperName,Label,Description,DataType,Length,Precision,Scale,ReferenceTo FROM FieldDefinition WHERE EntityDefinitionId = 'Account'

Why is the Description field not returning any values, while the query is not throwing any errors?

Kind regards,
Roel
