Integration xxxxxxxxx failed: API key not found

Hi All, hoping someone can help.
Doing the AWS integration as per the V3 stack documentation. Literally done it about 20 times.
Always get this message, cant do anything to get rid of it. API is def correct. Checked all settings multiple times, not sure what else to do. No info getting to AWS IoT.
