Hi @boydcster,
I suppose that you want to use “Log in History” action in Microsoft Flow, but the “Log in History” action is not supported in Microsoft Flow. There is an alternative way to see what is going on with your workflow variables in Microsoft Flow.
You could view the run history of a flow to see the value of a variable in Microsoft Flow, select a flow run from the list of runs to see the inputs and outputs of each step.
If the flow runs failed, there is a red exclamation icon in error step of run history. You could achieve error details from the failure step of run history.
If you want to view the value of a variable, you could expand the step to see details of inputs and outputs by clicking the step.
More details about viewing the run history of a flow, please check the following document:
Manage a flow
If you are a beginner of Microsoft Flow, I think the following document is helpful for you:
Guided learning of Microsoft Flow
Best regards,
Kris
