Hello! There's an error in a user profile I'm generating to configure an wireless internet connection. When I try to import it the Profile Manager tells me there's an error, and if I try to use the profiles utility I get the following error:$ profiles -v -I -F ./xxx.mobileconfig profiles: verbose mode ON profiles: using user name = xxx profiles install profile xxx.mobileconfig for user: xxx profiles install for file: 'xxx.mobileconfig' and user:'xxx' returned 3840 (The data couldn’t be read because it isn’t in the correct format.) profiles: returned error: 3840 failThis is the error you get if you try to import any file that's not valid, from an .mp3 file to a proper .mobileconfig file with a missing closing tag, so it's not very helpful.I've checked for obvious errors, like whether it's correct XML, whether there are any weird characters or whatever - didn't find anything. I've tried comparing it to a correct file but I haven't been able to find anything yet. Is there any way to get more detail about what's wrong? Some sort of tool, or at least the specification for these files? ThanksEDIT: Okay, I found the specification (https://developer.apple.com/library/content/featuredarticles/iPhoneConfigurationProfileRef/Introduction/Introduction.html), I'm going to look into this.
