Hi All,
I got an error when using Entity Store to export to Data Lake (using sandbox environments). I have updated the values in System Parameter Data Connections to point to my Dev data lake, able to successfully run the Test Azure Key Vault and Test Azure Storage tests on that form, but when we force a refresh on a model (or any model), I got (503) error.

What I did:
1. Followed steps in https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/data-entities/entity-store-data-lake
2. Run the tests "Test Azure Key Vault and Test Azure Storage" in the Data Connections form. (they succeeded)

3. Set a refresh of a model from the Entity Store form (e.g. AssetTransactionMeasure)
The D365 FO folders are populated in the data lake as below (but not data inside).


Any help is highly appreciated! Thank you!!
