Error: dynamodb: one or more parameter values were invalid: type mismatch for index key
What's Causing This Error
You may run into this error when you try to update and insert a new item to a DynamoDB table by using invalid data types for the attributes.
If you've pre-defined attributes (AttributeDefinitions
) to be used as the partition and range keys for your GSIs and table, you most likely selected a data type varying from a String, Number, or a Binary (Map).
Hence, the AttributeDefinitions
need to be preserved when creating or updating data.
Solution - Here's How To Resolve It
Verify that the attributes in your item are a part of the AttributeDenitions
which use the same data type specified during the creation time.
