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.
