Error: DynamoDB type is not supported
Answered by Rafal Wilinski
What's Causing This Error
This error is caused when an invalid data type is passed as a value for an attribute in a DynamoDB table. Each attribute in a DynamoDB table has a specific data type; passing a value of a different data type than the one specified will result in this error.
Solution: Here's How To Resolve It
To solve this error, you can take the following steps:
- Verify that the data type of the value being passed matches the attribute's data type in the table.
- Ensure that the attribute passed is either a number, string, boolean, binary. list or map. Presently, these are the data types that are supported by DynamoDB.
- Use CloudWatch logs to check the logs and troubleshoot the issue.
