My App service Azure http trigger functions have stopped to work correctly since July 14th. Only work inside Azure test tool portal. If I call the same http trigger function outside Azure (browser or web App) returns a 500 error. It receive the call but seems that not receive the body contents of the post. I 've had running without any problem the same Azure functions for months and suddenly form July 14th have started to failed.
Did you tried to connect your function app with application insights and see the logs ? Or even to use diagnostic & solve problems blade , here you can figure out for example if connection string used to access baked services are no more valid
Did you resolve it yet? You may re-create a new function and move the code under it. I tested it couple of time. I could not produce this issue but i am able to use HTTP trigger without any issues.
