Hello, I am deploying a new Flyte cluster with helm chart. I am able to run pyflyte run --remote. However the workflow failed to start remotely. And the error in propeller suggesting it’s not able to write the S3 bucket. From UI:

Workflow[customer-ds:development:<http://ml_project_1.test_env_vars.wf|ml_project_1.test_env_vars.wf>] failed. RuntimeExecutionError: max number of system retry attempts [51/50] exhausted. Last known status message: failed at Node[start-node]. CausedByError: Failed to store workflow inputs (as start node), caused by: Failed to write data [0b] to path [metadata/propeller/customer-ds-development-f829d772e914540dfa24/start-node/data/0/outputs.pb].: PutObject, putting object: AccessDenied: Access Denied

Note that each host id is different. When submitting the local workflow to remote via pyflyte run --remote, the flyte server is able to write to the same S3 bucket at

/metadata/customer-ds/development/f829d772e914540dfa24/

Why cannot the propeller write to /metadata/propeller/customer-ds-development-f829d772e914540dfa24/start-node/data/0/outputs.pb? Could someone shed some light? Thank you very much!

Have you double-checked the credentials you specified in the flyte binary or core configmap?

Hi @Samhita Alla, Sorry I didn’t see your reply until now. The issue was caused by wrong IAM role config on my end. Thanks
