Error: DynamoDB GetItem no item

GetItem returns no Item field when it finds no record at the requested primary key. That is a successful not-found response, not a validation error. Check the key and target first; a recently completed write may also be hidden by an eventually consistent read.

import boto3

table = boto3.resource("dynamodb", region_name="us-east-1").Table("Orders")
response = table.get_item(
    Key={"pk": "ORDER#123", "sk": "DETAIL"},
    ConsistentRead=True,
)
item = response.get("Item")
if item is None:
    print("No item at that key")

Use both keys when the table has a sort key, with exact case and value types. Confirm the write was awaited and succeeded, then compare account, Region, table name, and endpoint. A strong read does not create an item, prevent a later deletion, or wait for replication to a remote MREC replica.

If you only know an index key, use Query rather than GetItem. Avoid scanning the whole table as the first diagnostic step. Also check whether a projection requested only attributes absent from the item, and inspect TTL or application deletes when a record genuinely disappeared.

See key-based reads and AWS documentation.
