Hi I have a question: I'm using my laptop to code the flow, then I deploy it. After that I open my vps and run as Agent and seem like it not work

I think this doesn’t work because you didn’t specify a storage? The default Storage is Local which just saves it as a file locally. If you want it to be pulled by any agent, you need to store it somewhere like S3 or Github

My flow does not touch any storaged, it just call API and then call another API to save data

Yes because the Storage is where the Flow is stored and then the agent imports it from that Storage by default, it will be saved in something like

./prefect/flows/…

. But then your agent doesn’t have that file at that location (it’s on the computer you registered from). So it will try to import but fail

Thanks. This is the error

Yeah so all Flows need Storage, and registration puts the Flow into the storage. During execution, the Flow is retrieved from that Storage. When you registered on your computer, a file was created in the

Users/…

folder there. When you run it on the agent, it looks for the same path, but it doesn’t have that file.

thanks. Let me try it

I have an example here: https://github.com/kvnkho/demos/blob/main/prefect/git_storage.py

Hm now I got the error. Do I need to install anything else on the agent host?

Yeah you seed to install the github extra

pip install prefect[github]

or you can install pygithub

Success now. Many thanks!
