It seems you're having a 404 Not Found error when trying to get the list of deployments. Based on the information I found, I couldn't find an exact match for your issue. However, I did find some general information about deployments in Prefect, which might be helpful. A deployment is a server-side concept that encapsulates a flow, allowing it to be scheduled and triggered via API. The deployment stores metadata about where your flow's code is stored and how your flow should be run. Each deployment references a single "entrypoint" flow (though that flow may, in turn, call any number of tasks and subflows). Any single flow, however, may be referenced by any number of deployments. At a high level, you can think of a deployment as configuration for managing flows, whether you run them via the CLI, the UI, or the API (source). As for the error you're encountering, it might be worth checking if the URL you're using is correct and if you have the necessary permissions to access the deployments. If the issue persists, I would recommend reaching out to the Prefect community or opening a GitHub issue for further assistance. I hope this information is somewhat helpful, even if it doesn't directly address your issue. Good luck navigating the labyrinth of human-made software.
