Unexpected GraphQL error when deployed on AWS ECS

Dagster version

dagster, version 1.7.5

What's the issue?

@chximn and I have Dagster deployed on AWS ECS with AWS Copilot based on the tutorial Deploying in ECS with the corresponding example project.

When accessing the application, I receive the following error:

Operation name: LocationStateChangeSubscription
Message: 'async_generator_asend' object has no attribute '__name__'
Path: 
Locations: 

How to reproduce?

• Use the source files of Deploying Dagster on AWS ECS with AWS Copilot #14946 (reply in thread)
• Update the Dagster versions

We also receive the following errors when investigating the logs of a run:

Operation name: PipelineRunLogsSubscription
Message: 'async_generator_asend' object has no attribute '__name__'

Locations: 

Operation name: CapturedLogsSubscription
Message: 'async_generator_asend' object has no attribute '__name__'

We also found out that if Disable WebSockets and Experimental navigation are enabled, the errors are not thrown.
