Could you please try with the newest release that includes a newer Docker CLI?

In my case, this error occurred when Shepherd attempted to update a service where the newly pulled Docker image had an issue with its startup script.

However, I believe the most appropriate course of action is for Shepherd to disregard such errors and proceed to the next service.

Docker v29.0.2
