hi, we are geting this error in the logs and have no clue why, we have a lambda which does a scan on dynambd, the lambda seems to throw an error count at the time, there seems to be nothing in dynamdb, this is the error, can anyone tell me why this is happening?

}
i'm not sure it is that, as at the exact same time a CORS error is thrown, would the CORS error cause a limit rate?
From the error message, it does not look like having to do with CORS. The error is being thrown when the lambda function is trying to do a scan on DynamoDB and from the error message what I can see is that the filter expression max length is being violated.
I'm getting the same error when trying to update a item via the management console:
Invalid ConditionExpression: Expression size has exceeded the maximum allowed size; expression size: 4255The item has 17KB which is way lower than the 400KB limit for items in DynamoDB.
