Error: DynamoDB validation error
Answered by Rafal Wilinski
What's Causing This Error
This error can be caused by a variety of issues, such as:
- Attempting to write an item that exceeds the attribute value size limit of 400 KB.
- Attempting to write an item with attribute values that exceed the limit of attribute value size of 1 KB.
- Attempting to write an item with an attribute of the wrong data type.
- Attempting to write an item with an attribute not defined in the table schema.
- Attempting to write an item with a primary key value that already exists in the table.
- Issues with the IAM role associated with the request.
- Errors with the SDK being used.
Solution: Here's How To Resolve It
To solve this error, you can take the following steps:
- Check the size of the item and the attribute values, and make sure they don't exceed the limits set by DynamoDB.
- Check the data types of the item's attributes and ensure they match the data types defined in the table schema.
- Check the item's primary key value and ensure it is unique and not already used by another item in the table.
- Check the IAM role associated with the request to ensure it has the necessary permissions to write to the table.
- Verify that the SDK being used is configured correctly and that all necessary dependencies are installed.
