My user data us being sent to cognito and dynamodb and all backend is working correctly but on the front end i'm getting that erorr. Any suggestions?

Check Userpool whether it has pre-sign-up lambda enabled. If so, the check the lambda return value. https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-pre-sign-up.html

This is the best guess based on the symptoms described.

Providing more details around the errored API and its console log might be helpful.
