Hey folks! My team runs Dagster on ECS and I’m looking for some help integrating with the Dagster Graphql Client. I recently deployed an AWS lambda that uses the Python client to trigger a job run on the ECS service with the

submit_job_execution(job_name=)

method. This works locally, but hangs when deployed. I’m trying to suss out why this is the case

Sounds like a networking issue - have you checked to make sure that you have a security group on your Dagster ECS service that allows inbound from a security group placed on the Lambda? Are they in the same VPC?

This sounds really promising. The lambda is not part of the same VPC. I’ll give that a shot. Thank you!

That will definitely cause an issue

Bingo. That was the issue. Very much appreciate the help

No worries - I now look back with slight fondness at my memories of pulling my hair out debugging Lambda VPC connectivity issues
