Mavic Error After Takeoff "Check App" No Log

[mobalized]

When I was out flying on a pier at a nearby lake today I took off and immediately got an error (which I can't seem to remember the exact wording), the controller said to check the app and the status light on the Mavic was solid Red. The app wasn't indicating any error at the time, I brought the quad back over to myself and then started seeing compass errors which I assume is due to the nearby water break which is steel. I landed it, restarted it and flew without anymore substantial issues aside form a blinking controller icon.. I assume this was all caused by some sort of interference or metallic objects. But I through the log file into Phantom Log Viewer and it doesn't indicate any errors during that 1 minute flight. Any thoughts?
