The queryservice-ui spams these kind of logs every time it tries to read the non-existing custom-config.json file
This is just a hassle to have logged with since it's probably not a "real" problem and probably something we could fix in the code to make it not log this as an error.
[error] 32#32: *57975 open() "/usr/share/nginx/html/custom-config.json" failed (2: No such file or directory)
AC
- Make these log lines not appear
- (Optional) Fix this in the queryservice-ui code
