TYPO3 12.4.16 or 13.2+ - 2024-06-23

The Issue

Cannot log into the TYPO3 backend.

With detailed error logging enabled, you get:

vendor/typo3/cms-core/Classes/TypoScript/Tokenizer/Line/IdentifierFunctionLine.php, line 83:
Function value token stream has not been set

Solution

The "page" cache needs an update due to a change in TYPO3 v12 (and v13), see https://github.com/typo3/typo3/commit/837f5b0b55.

The error should go away after clearing your TYPO3 cache either via Install Tool or CLI (vendor/bin/typo3 cache:flush), or manually deleting the folder var/cache/code.
