why is it that when I am using the dataset rest api endpoint, and query for the results of a dataset, I am not getting all the columns in the dataset

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** The issue you're experiencing with not getting all the columns in the dataset when using the REST API endpoint to query for the results of a dataset could be due to a few reasons: 1. Null Values: If a custom field has a null value, it may not be returned in the results. This is a known behavior of the NetSuite API. 2. Field Selection: The API call might be limiting the number of columns it should return. You might need to specify in your API call to include all columns. 3. Complex Joins: If your API call is carrying out complex joins, it might be causing some columns to be omitted. It might be more efficient to retrieve each of the entities' data separately and do the joining on your destination database. 4. Saved Search Configuration: If you're using a saved search to get the results, the configuration of the saved search might be causing some columns to be omitted. Make sure that all the columns you want are included in the saved search. Remember to always double-check your API calls and saved search configurations to ensure they're set up correctly to return all the data you need.
