Building flows

Hi @SO-11030637-0,

Your Filter array returned zero items, so [0] fails. The fix has two parts:

1)Why is the array empty? (diagnose and correct the filter so it returns exactly 1 policy)
2)Guard your expression so the flow doesn’t crash if a match isn’t found (good hygiene even after you fix the filter).

Before using it, check if it has a value at 0 index in a condition: body('Filter_array')[0]['defaultConnectorsClassification']

length(body('Filter_array'))

Like below example:

if true, then you have value in it and you can use it, if false they you have not received a value, might me a misconfiguration in filter.

Common reasons for no matches

Wrong property name: e.g., you filtered on name but the JSON has displayName.
Case/whitespace mismatch: “Finance DLP” ≠ “finance dlp”.
Wrong scope: Tenant policy vs Environment policy. If you’re cloning an environment policy, make sure the List action is scoped or filtered correctly by environment.
Not in this geo/tenant: Verify you’re in the correct environment/region.
Permissions: The “Power Platform for Admins” connector requires sufficient admin rights to list tenant policies.
