Question

In 2 0 how could I manually run a flow replay a flow run to be able to use pdb for debugging purposes I have tried `python m prefect engine lt flow run id gt ` but I get `This run has already terminated`

Kevin Kho · Answer

This is not possible because the flow already ended You can t rerun a finished flow like that but there are thoughts to expose something like that eventually

how could I manually rerun it is there a flag or something i could pass in the cli

Kevin Kho · Answer

What are you trying to do The flow failed so you want to inspect it at some point

Paco Ibañez · Answer

i would like to add a pdb breakpoint to the flow code and run it from the cli so I can debug

Paco Ibañez · Answer

or what would be the best way to troubleshoot a flow that fails before outputting any logs I can see the agent picking up the run but then the only thing I see is `prefect flow runner docker Flow run container spiffy husky has status exited `

Paco Ibañez · Answer

I am pretty sure the issue has to do with pydantic parameter validation I just would like to debug whats going on

Kevin Kho · Answer

A couple things you can try to get more insight 1 `prefect deployment execute lt flow name gt lt deployment name gt ` to see if this shows the error 2 Set `PREFECT DEBUG MODE=1` 3 Or maybe `docker logs lt container gt `
