Executable being called by an Azure function stopped working
I have a very basic azure function that when it receives a data file being sent through an app, it triggers the function which calls 2 executables and generate a PDF as a result. The executables are stored in a folder on a virtual machine running windows. Without doing any modification to the functions code, the executable or the virtual machine, one of the executables stopped working on Friday. If I download the executable to my windows PC and try to run it it does so correctly but when called in the VM it does not. I already tried replacing the executable on the VM with the one running on my PC to no avail. It has been working fine for years until Friday. Any ideas on how to solve this issue?
