Dagster Docker Key Error

[fredonia88]

I am trying to build dbt seeds and models with Dagster, which I'm running in Docker on version 1.10.21. I have deployed the project to an EC2 and am using two separate RDS Postgres instances for Dagster and dbt. When I try to materialize an asset that builds a seed or model (any asset in the pipeline), I get the same below key error:

KeyError: 'model.dbt_*****.stg_mvp__monthly_quota_sample'
  File "/usr/local/lib/python3.11/site-packages/dagster/_core/execution/plan/utils.py", line 57, in op_execution_error_boundary
    yield

    dbt_resource_props = manifest["nodes"][unique_id]
                         ~~~~~~~~~~~~~~~~~^^^^^^^^^^^

If I start a bash session in the grpc container and inspect the manifest.json, I can see the key 'model.dbt_*****.stg_mvp__monthly_quota_sample' in nodes. I can also run dbt build successfully from this container. When I run the project locally against a Postgres database running as a container, everything works just fine.

Any ideas what might be causing this? Or how else I can debug this? I've tried downgrading to Dagster 1.9 and get the same error. I'm at a loss. Please help!
