Environment variable in great_expectation.yaml not being replaced

GX Core (OSS) Support

I have configured confluent data source, like below. Where I want where condition to be completed using environment variable. This substitution is not working. Is this expected behaviour.

fluent_datasources:
my_snowflake_datasource:
type: snowflake
assets:
query_asset:
type: query
query: select * from table2 where col1 = ‘$col1’

The error I get is
(snowflake.connector.errors.ProgrammingError) 100038 (22018): Numeric value ‘$col1’ is not recognized
[SQL: CREATE OR REPLACE TEMPORARY TABLE gx_temp_bc9445ba AS SELECT *
FROM (SELECT * from table2 where col1 = ‘$col1’) AS anon_1
WHERE true]
(Background on this error at: Error Messages — SQLAlchemy 1.4 Documentation)

variable is set using. export col1=2

Datasource: Snowflake
Execution: Local CLI on Linux
GE Version: 0.18.1

Hi @skamalj, thanks for reaching out, and welcome to the community!

Yes, this is expected behavior. GX currently supports environment variable substitution as shown above for Data Source connection strings, but not yet QueryAsset queries.
