I have a next js client application with google managed custom domain from goDaddy, i want to redirect my http traffic app.test.com to app.test.com when i explicilty hit with http it does not redirect to https that i want to do. backend is in dot net core handled separately
app engine flex has no effect of below both these in app.yaml

how can i redirect http trafic to https?

Tried with these two fields in app.yaml but not success
