TYPO3 Core

Do you have other finishers activated? For example, the redirect finisher? If yes, the redirect finisher has to be executed at last of all finishers.

closing this.

imo it is fine as it states for the redirect finisher

This finisher stops the execution of all subsequent finishers in order to perform the redirect. Therefore, this finisher should always be the last finisher to be executed.

it doesn't make sense to write at all other finishers that it must be placed before the redirect finisher.
