@Expiscornovus Following on from my previous issue (https://powerusers.microsoft.com/t5/Building-Flows/Search-for-job-title/m-p/1495842) where you helped me tremendously, now I am trying to get the email address from the resulting output. Instead it is returning a Null even though it can be seen clearly that it is extracting the email address.

In Send an HTTP request, this is the string:
https://graph.microsoft.com/v1.0/users/?$select=mail&$filter=jobTitle eq 'ACIO'
The Parse JSON step produces this output
{
"@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users(mail)",
"value": [
{
"mail": "user@domain.edu"
}
]
}
Where user@domain.edu is actually the correct email address I want.
The Apply to each is

And Set variable is setting the value in
items('Apply_to_each_3')?['mail']
but this is coming up as Null.
Please help, what do I have to do to get the email address into the variable?
Thanks,
Anne
