Error on package:discover

[TwilightDuck]

This occured after a composer update. I do not have the configuration file published.

   ErrorException

I am also experiencing this issue in one of my environments (but not locally). I have the format option set to atom but it's still giving me this error.

I have the same problem, but only on production, not locally. I have no config at all, I wasn't even aware of having this package in my dependency tree. Furthermore, I found out that this package require laravel-feed: spatie/laravel-mailcoach.

PHP on production:

I'm also experiencing this exact issue on upgrading Mailcoach from v3 to v4. I have published the configuration file, but still see the error. Any ideas on this @freekmurze ?

If you'd check vendor/spatie/laravel-feed/src/Helpers/ConfigurationValidator.php:15 you will notice that it checks for the format key in each feed you have defined. So make sure you have it added to each custom feed inside config/feeds.php. This wasn't mandatory before btw.

This is it!

It usually happens after upgrade. Thanks!

How do you do that, could you show?
