When opening Nextcloud in the browser, i receive a 500 response code.

Curl output:

$ curl -i https://my-domain.tld

HTTP/2 500
server: nginx/1.18.0 (Ubuntu)

Today I switched the docker container hosting nextcloud-aio (I created a new one and deleted the old one, to switch to docker-compose and change some exposed ports).
To my surprise, the new Nextcloud picked of the old data (same backups, passphrase etc).
So I updated all containers. The dashboard gives me “healthy” status for all of them, however when I open nextcloud in my browser I get a 500 error.

I think it has something to do with this error log from the nextcloud container:

NOTICE: PHP message: PHP Fatal error:  Declaration of OCA\WebAppPassword\Controller\ShareAPIController::createShare(?string $path = null, ?int $permissions = null, int $shareType = -1, ?string $shareWith = null, string $publicUpload = 'false', string $password = '', ?string $sendPasswordByTalk = null, ?string $expireDate = null, string $note = '', string $label = '', ?string $attributes = null, ?string $sendMail = null): OCP\AppFramework\Http\DataResponse must be compatible with OCA\Files_Sharing\Controller\ShareAPIController::createShare(?string $path = null, ?int $permissions = null, int $shareType = -1, ?string $shareWith = null, ?string $publicUpload = null, string $password = '', ?string $sendPasswordByTalk = null, ?string $expireDate = null, string $note = '', string $label = '', ?string $attributes = null, ?string $sendMail = null): OCP\AppFramework\Http\DataResponse in /var/www/html/custom_apps/webapppassword/lib/Controller/ShareAPIController.php on line 109

However I could not find any mention of this error elsewhere online.
