Error: DynamoDB GetItem no item

Answered by Rafal Wilinski
What's Causing This Error
This error is caused when retrieving an item from a DynamoDB table using the get_item()
function, but the item does not exist in the table with the primary key value specified in the request.
Solution: Here's How To Resolve It
To solve this error, you can take the following steps:
- Verify that the primary key value specified in the request is correct and exists in the table.
- Check the primary key value by using the scan() or query() operation to retrieve all items in the table and verify whether the item you are trying to retrieve is present in the table.
- Ensure that the primary key value passed in the request matches the primary key schema defined in the table.
- If the item is not present in the table, you can insert it.
- If you need to ensure that the item is present in the table before performing any operation, you can use
get_item()
function withConsistentRead
parameter set to True.
