Error: could not lookup table in dynamodb

Could not lookup table is usually a library or tool message wrapping a failed table lookup. Read its underlying exception to distinguish a missing table from access denial, invalid credentials or network failure.

aws dynamodb describe-table --table-name Orders --region us-east-1

1. Run the check with the same credentials and endpoint as the application. Use the physical table name and exact capitalization.
2. If ResourceNotFoundException is returned, verify account, Region and whether the deployment created the table.
3. If access is denied, check dynamodb:DescribeTable permission and effective policy restrictions. Data permissions do not necessarily allow metadata discovery.
4. If the table is still being created, wait for ACTIVE before data operations; if lookup times out, repair connectivity first.

For DynamoDB Local, also compare the local port, sharedDb setting and database location. Avoid creating a replacement table automatically when an unknown lookup error occurs, since that can hide a configuration problem.

See table setup and AWS documentation.
