Hey @zainab !
It has been some time since we have heard from you so I am going to archive this topic. If you still need help please feel free to repost your question at the top of the community.
I would also recommend creating a support ticket if you believe you are encountering an error with SageMaker Canvas. Here are the steps to open a support case. If your company has someone who manages your AWS account, you might not have direct access to AWS Support and will need to raise an internal ticket to your IT team or whomever manages your AWS account. They should be able to open an AWS Support case on your behalf.
