I updated v2021.0.5 from v2021.0.4 and I’m now getting Error 500
When I look at the error log it shows:
PHP Fatal error: Interface ‘Slim\Interfaces\ErrorHandlerInterface’ not found in [path to my site]/vendor/slim/slim/Slim/Handlers/ErrorHandler.php on line 47

Are you using old Composer? Read https://discourse.hkvstore.com/t/interface-psr-http-message-requestfactoryinterface-not-found/3419/1 may update to the latest Composer (v2.0.7 as of today) and try again.

That seems to have fixed it.
Thanks!
