Dagster Pipeline Failed with LaunchFailedError - not found in the documentation?

[ge0f0rc3]

Hi All - I have created a series of dagster pipelines, and most were working successfully until I received the failure below for one of my pipelines.

Note - I have resolve the below by reloading the workspace, and running the pipeline again, but figured the information below might be useful for others.

Error from Failed Pipeline:

Error when trying to run Failed Pipeline again:

I have checked the formal documentation to find this sort of error, but have been unable to find anything. Even various searches across the internet have yielded no results.

I've run these pipelines previously, and they have operated successfully - the code has not changed either. One potential thought was it could be related to port blocking of another pipeline that is running at the same time. Although, I have had independent pipelines run at the same time successfully without this issue previously.

Has anyone else encountered this issue before? Any ideas would be greatly appreciated.

Cheers.
