Re: erro no teste de fluxo
HI @JulioCesar,
I will move your cases to Power Automate forum, please focus on Power Automate forum if you have questions related to flow next time.
For your flow, you have it as the cloud flow, which needs you trigger it based on data, which means that you need to create an item in your SP list so that your flow will be fired.

Click the manually trigger and then go back to your SP list and create a new item.
