We have several apps using environment variables which hold the connection information to the underlying SharePoint lists.
I have observed that we receive user complaints about error messages or data not loading. Most of these issues go back to the values in the environment variables being wrong. Sometimes the "list" field is empty, sometimes it contains a number (the list ID in SharePoint?). When I reset the variables to the correct value things work fine again - until next time.
Interestingly enough, it is never the environment variable for the site but always the list ones.
How can that happen? Is there some sort of log where I can see whether people go and change the values?
