VIEW JSON result value in view which based on volume

[Cami]

Hello guys!

I have the following case:

It has been decided that the json file will be read from a following definition ( from volume) , which more or less looks like this:

CREATE OR REPLACE VIEW  [catalog_name].[schema_name].v_[object_name]
AS
SELECT result, _metadata.file_path  as etl_full_path, _metadata.file_modification_time as etl_inserted_at  FROM json.`dbfs:/Volumes/[catalog_name]/[schema_name]/[volume_name]/object=[object_name]/`

I would like to read this view using SQL warehouse and I can not view result column value - there is a  NULL value 

despite the flag is turn on  in view properties.

view.sqlConfig.spark.sql.legacy.json.allowEmptyString.enabled=true

Any tips?

Thank you for response.

But there no issue with NULL value when I query view created on my cluster which has set the flag

spark.sql.legacy.json.allowEmptyString.enabled = True

Without that flag on session or cluster I get NULL value querying json.
The issue with a NULL value occurs when I query view via SQL warehouse compute.
