I'm getting a weird error even though my flow exists

Copy code

prefect.exceptions.MissingFlowError: Flow 'tool' not found in script 'flows/tool.py'. Found the following flows: 'monolithic-tool-flow'. Check to make sure that your flow function is decorated with `@flow`.

I have the flow defined as

Copy code

flows/tool.py
-------
@flow(name="monolithic-tool-flow")
def process_tool()...

and deploy like

Copy code

prefect deployment build flows/tool.py:process_tool -n process_tool  -q test -ib docker-container/local --override image=sha256:4e3346168cs3a3c6c0fb256d6e705c6629a41f0f6f23405c33a0bbc3deb964690   --apply

Weirdly, renaming the flow worked.

I think this might be related to the 2.7.2 release. I just updated my images and I'm getting these errors as well

I'm guessing it has to do with the changes introduced in this PR: https://github.com/PrefectHQ/prefect/pull/7817 I reverted back to 2.7.1 on my flow run images, and things are back to normal.

its seems that flow name with underscore in the function name do not work, as deployment build command tries to find the flow with dashed case instead of underscores
