I am, seemingly at random, receiving 404 not found errors on azure function calls from within ADF pipeline. They occur once every 10 runs, roughly, and come in two forms:
The first has this HTML as its error:
Call to provided Azure function 'Parse' failed with status-'NotFound' and message - '<html> <head><title>404 Not Found</title></head> <body bgcolor="white"> <center><h1>404 Not Found</h1></center> <hr><center>nginx</center> </body> </html> '.
The second is:
Call to provided Azure function 'Parse' failed with status-'NotFound' and message - 'Invoking Azure function failed with HttpStatusCode - NotFound.'.
These are interspersed within successful runs and rerunning the pipeline with the same triggered file (this a blob upload trigger) will run with no problems suggesting that it is not an input issue. Furthermore, the fact that they occur 2 seconds means it is not a timeout issue? Any thoughts?
