Error creating aws_s3_notification with Terraform - amazon-web-services

Question

I'm currently having an issue with my aws_s3_notification resource creation. Whenever I attempt to deploy this resource, I receive this error
Error putting S3 notification configuration: InvalidArgument: Unable to validate the following destination configurations
I've tried setting depends_on parameters and adjusting permissions. One interesting thing is in my main.tf file, I'm creating two lambda functions. Both are extremely similar (just vary by code). My "controller" configuration deploys with no issue but my "chunker" function seems to have an issue creating the s3_notification.. I have included both configs for comparison.

UPDATE: If I manually create the trigger and run terraform apply again, terraform is able to move forward with no problem....
