Dear Vivian,

UC is not enabled on this workspace . I am using Instance profile set up as per databricks document .

S3 is set up for cross account and as i said , i am able to run dbutils.fs.ls("s3a://zuk-comparis-poc/")

But when i run the workflow which envoks a delta notebook ,it gives me this error.

This is a standard cluster , so i have not enabled IAM passthrough.

Am i missing something . Thanks in advance
