D365 Sales - Close opportunity as lost - Common da...

Hi everyone,

So I'm trying to create a flow from Dynamics 365 Sales that would allow me to close opportunities in batches as Lost .

The first issue I have is that my Sandbox environment is connected to my production environment in terms of flows... When I click on Create a flow from the opportunity view in my Sandbox, it connects to my power automate production site. I tried to force a change of environment without any luck.

The second issue is that I have no clue where to begin (to be honest). I was used to the Dynamics 365 connector but since the change to the common data service, I'm kind of lost.

Below is what I have, but I get Unexpected error.

Any idea would be great.
