I have a flow which stopped working recently (13 Nov on the UAT Flow) and (15 Nov on the Prod flow). After debugging, I found out that the Power Automate trigger is skipping the x-api-key on the header. When I change the x-api-key to x-api-key2, it starts appearing on the flow header. I want to know if it is now a reserved keyword, that Power Automate trigger is skipping 'x-api-key'.
Kindly share your thought if there is any change, or same happen to anyone recently.
