Error: dynamodb 1 validation error detected value
Answered by Rafal Wilinski
What's Causing This Error
You may run into validation errors whenever there is an issue with the expression passed into a DynamoDB operation. For example, you may run into this error if you pass in the KeyConditionExpression, UpdateExpression, or a Segment parameter wrongfully.
Solution: Here's How To Resolve It
Since there is no background on the actual DynamoDB operation executed, it can be challenging to determine the exact solution. Therefore, the best option at this stage is to evaluate the expression passed into DynamoDB and ensure that you have provided it correctly.
Additionally, if you are trying to execute an update on nested attributes in DynamoDB (SET stats.total = stats.total + 1000), ensure that the stats (parent node) exists in the DynamoDB item. The parent must exist before updating its child node. Finally, in such cases, use validation functions such as if_not_exists() to initialize your values if they are empty in the database.
