2 things to check
1. I cannot see your Flow action, so can you please verify that you are actually capturing the outputs IN there? You would have to open the action to show it, as that is where you would define your Variable to capture the output and make it part of the Topic.Variablehere accessible (under custom).
So please share that picture
2. I know you said you were cleaning up, but what is the body content coning from, as I see the For each (cannot see anything on the inside of it) but jus want to make sure you are actually passing back what you think you are,
So to call your Power Automate you should
1. Select the Tool
2. Define the inputs
3. Define the outputs
--assign to a Variable
Thats what I am looking for
Also, lastly look at your Flow, verify that your Body Content actually has data
And put a description in for it.
If these suggestions help resolve your issue, Please consider Marking the answer as such and also maybe a like.
Thank you!
