TER - Keeping expiring extensions ends in "Oops, an error occurred!"
Summary
I try to keep one of my expiring extension keys in the TER. I click on the button "keep" but the action ends in "Oops, an error occurred!
Steps to reproduce
Go to the expiring keys section at https://extensions.typo3.org/my-extensions/
This call breaks: https://extensions.typo3.org/my-extensions/?tx_terfe2_pi1%5Baction%5D=keep&tx_terfe2_pi1%5Bcontroller%5D=Registerkey&tx_terfe2_pi1%5Bextension%5D=18844&cHash=89acf1bbac0143e76a...
What is the expected correct behavior?
I should be able to keep my extension keys when they are about to expire.
