this is the log when deploy to fly io
Hi,
Unfortunately that line only says there was an error, not what the error actually was.
I’d recommend trying fly logs - that should show the latest X lines of the log for the app. That will often reveal what went wrong e.g out of memory, file not found, module not loaded … etc (depending on your app/language/dependencies). Lots of variables. But some kind of error message should point you towards the fix.
