I added a $has_many relationship to Page.php, which worked fine in SS3.6, but now I get an error when I dev/build it breaks at the ErrorPage: [Emergency] Uncaught InvalidArgumentException: has_many relation SilverStripe\ErrorPage\ErrorPage.HeaderImages references class HeaderImage which doesn’t exist
and when I try to open the page in the browser it’s: [Emergency] Uncaught InvalidArgumentException: has_many relation MyNamespace\HomePage.HeaderImages references class HeaderImage which doesn’t exist
I have on the HeaderImage private static $has_one = [‘Page’ => Page::class] and on
Page.php private static $has_many = [ ‘HeaderImages’ => HeaderImage::class] so nothing really changed between SS3.6 and SS4.5
Why doesn’t it work anymore?
Has anybody any idea?
