I'm trying to deploy a new prefect-agent on the latest version of prefect using the prefecthq managed chart - I'm able to get my agent deployed but I'm running into a 404 error upon deployment:

raise PrefectHTTPStatusError.from_httpx_error(exc) from exc.__cause__
prefect.exceptions.PrefectHTTPStatusError: Client error '404 Not Found' for url '<https://api.prefect.cloud/api/accounts/><MY_ACCOUNT_ID>/workspaces/<MY_WORKSPACE_ID>/flow_runs/filter'
Response: {'detail': 'Not Found'}
