we found a bug in 9.5.17 in core files.
It is thrown wenn the BE user has access to many groups because there are a lot restricted sites. The string that is created in our case is

"PageRepository_groupAccessWhere_pages_fe_group_pages_0_-2_3_4_5_6_20_35_37_46_52_53_82_907_1017_1018_1020_1022_1110_1179_1671_1672_1673_1674_1675_1676_1677_1678_1679_1680_1681_1682_1683_1684_1685_1686_1687_1688_1689_1690_1691_1727_1775_1815_1817_1818_2103" 

it is too long

this commit should be overthought
[TYPO3 Github Commit](https://github.com/TYPO3/TYPO3.CMS/commit/34fcc2dc9e4d88ed3a33f9a8b0c8d860e304946d#diff-bdefdf9381ae0d42c73398fe045a53cb)

Problem is const

/**
 * Pattern an entry identifer must match.
         */
        const PATTERN_ENTRYIDENTIFIER = '/^[a-zA-Z0-9_%\\-&]{1,250}$/';

in file
/typo3/sysext/core/Classes/Cache/Frontend/PhpFrontend.php

if system is configured for restricted access wich is manged by groups and some user got a lot access and the use in function

/**
 * Checks the validity of an entry identifier. Returns TRUE if it's valid.
 *
 * @param string $identifier An identifier to be checked for validity
 * @return bool
         */
        public function isValidEntryIdentifier($identifier)
{
            return preg_match(self::PATTERN_ENTRYIDENTIFIER, $identifier) === 1;
        }

in file

/typo3/sysext/core/Classes/Cache/Frontend/AbstractFrontend.php

that is called from

/**
 * Finds and returns a variable value from the cache.
 *
 * @param string $entryIdentifier Identifier of the cache entry to fetch
 *
 * @return mixed The value
 * @throws \InvalidArgumentException if the identifier is not valid
         */
        public function get($entryIdentifier)
{
        if (!$this->isValidEntryIdentifier($entryIdentifier)) {
            throw new \InvalidArgumentException(
                '"' . $entryIdentifier . '" is not a valid cache entry identifier.',
                1233058294
            );
        }

and throws the error because our given value is longer than 250 chars

table cf_cache_pages
identifier Index varchar(250) utf8mb4_unicode_ci
