Running into problem registering flow created in non ` main

Question

Running into problem registering flow created in non ` main ` moved code blocks into thread

Chris White · Answer

Hi Scott can you please create a Slack thread for all of these tracebacks and code blocks so the main channel remains tidy

Chris White · Answer

Otherwise your Flow needs to be created in the main script body if you are using script based storage The script will be rerun by a non main process which means the flow definition and corresponding attributes need to be available outside the `if name == main ` block

If I create a flow in main but add tasks to it in a module is that ok

Chris White · Answer

Yup so long as a rerun of the script itself when ` name ` is not ` main ` produces the Flow object that you expect

ok gotcha so that s a way to test
