@abimnyud Did you find an alternate option for this? And if not is this solution still working for you?
I have tried your solution but it isn’t working for me. I end up in a redirect loop where App Engine just issues a series of 302 redirects back to the same page over and over until the browser steps in and errors with “The page isn’t redirecting properly”.
I am running Strapi as a microservice in my multi-service GCP project, it isn’t the default service so the routing is via the -dot- notation e.g. https://cms-dot-.appspot.com/_ah/warmup. Is this similar to what you are doing or are you running on the default service?
In my search I also came across this but can’t make that work either.
Any tips/pointers?
