The following sections describe common errors that might occur when you create a share or access data in a share.
The following errors are common when accessing data in a share.
Issue: You see an error message that throws a file not found or certificate exception.
Possible cause: Your bucket name uses dot or period notation (for example,
incorrect.bucket.name.notation). This is an AWS limitation. See the AWS bucket naming rules.
Recommended fix: Use a different bucket for Unity Catalog and Delta Sharing.
