Error in Fargate configuration file: FargateECSTaskDefinition

I'm using sls with AWS Fargate. I'm trying use sls deploy -v but am getting an error in my fargate-template.yml when I try to set the Memory property under FargateECSTaskDefinition. Here's the relevant yml section:

FargateECSTaskDefinition:
    Type: "AWS::ECS::TaskDefinition"
    Properties:
      Cpu: 256
      Memory: 512 MB

And here's the error I get:

An error occurred: FargateECSTaskDefinition - Resource handler returned message: "Invalid request provided: Create TaskDefinition: Invalid 'memory' setting for task. (Service: AmazonECS; Status Code: 400; Error Code: InvalidParameterException; Request ID: f4d1c13d-1885-4157-bf21-4299b06cf3ff; Proxy: null)" (RequestToken: b872e59f-4329-35ed-5191-cfb0c486f49f, HandlerErrorCode: InvalidRequest).

Setting Memory: 1GB works without a problem. I tried both Memory: 512 MB and Memory: 512MB, thinking that the space would make a difference. Both returned an error though. I'm following this documentation, which suggests that a combination of 256 CPU units and 512 MB memory is compatible, so I'm not sure what the issue could be.

The difference between 512MB and 1GB is trivial from a cost perspective, but at this point I want to solve this on principle.

In CloudFormation the valid values are listed here. It should be:

FargateECSTaskDefinition:
    Type: "AWS::ECS::TaskDefinition"
    Properties:
      Cpu: 256
      Memory: 512
