hey everyone. i’m suddenly starting to get this error on my flows:

AttributeError: 'Flow' object has no attribute 'terminal_state_handler'

any idea what could be the reason? i’m running on prefect self hosted server

Hi @Dotan Asselmann, i believe people saw this error when 0.14.16 was released and their Flow version was higher than the server version. In general, Prefect server version and agent version must be higher than the Flow version so I would check all the versions

thanks
