I'm trying to get data from a delta table in Azure Databricks using Data Factory. I followed this doc [link](https://learn.microsoft.com/en-us/azure/databricks/data/data-sources/azure/adls-gen2/azure-datalake-gen2-sp-access#access-adls-gen2-directly) to mount the storage and I'm using a service principal to access to the storage.

I can "preview" the data in the copy activity but when I try to transfer I get this error:

Failure to initialize configurationInvalid configuration value detected for fs.azure.account.key
Caused by: Invalid configuration value detected for fs.azure.account.key.

I even give **contributor** role to the APP and the ADF in the Databricks resource

I'm running without more ideas, so any one has tried to do this ? Thanks in advance
