Power Automate - iAuditor integration to Excel for business

Hi all,

I'm trying to build a flow in Power Automate to feed data in Excel file (located on SharePoint) used for my Power BI report but i don't know why it does not want to work.

This is my flow as shown in the photo

In the first "For Each" action i have " body('Site') ", second " body('Serial Number') ".....

When i test this is how it looks like

If i remove the second and third FOR EACH, it goes to the excel action and stops there.

Does anyone have a similar flow or does anyone know what i'm doing wrong?

Thank you in advance if anyone has a solution.
