My current scratch org is expiring today, so I created a new scratch org and tried to push my source. It seems like it's working on the task for a minute or so, then gives me an error with no detail:
ERROR running force:source:push: Push failed.
I don't have a clue how to troubleshoot this. I'm pushing a substantial amount of code, custom objects, permissions, etc., so I'm used to having to tweak my .forceignore file to get things to push. But usually, there is detail in the error that tells me what needs to be adjusted.
I'll try using deploy on some things instead and see if that works.
Not sure if this is related to Summer '19, though my previous scratch org updated and things were working well there.
