I am trying to create an automation to update the sharepoint list whenever an unsubscribe email is received in the inbox. However, the flow stops at "Apply to each 4". When I click on it, it's just a greyed-out box (see below).

According to another website, it means the data returned from the previous field is empty. The value I'm retrieving is from the "Get Emails".

I'm pretty sure the returned value is not empty though, because I've also used the same value for extracting the sender's address. As seen below, the value is returned correctly. It should mean that the 'value' of "Get emails" is not empty.


So I am confused on where the problem is, since the flow isn't returning any error message either.
Any idea what's wrong? I'd appreciate any help, thanks 🙂
