This screenshot does not help, because it gives me a truncated info (I cannot scroll the page inside it or expand collapsible sections).
Please provide the textual representation of the stack trace instead (available in the Stack trace tab). And please actually provide it as text, not as a screenshot containing text.

Please also describe on which page you get this error (and which action you are doing) to allow reproducing the issue.

the problem is in this code:

               // if (null === $post->getSlug() && null !== $post->getTitle()) {
                //     $post->setSlug($this->slugger->slug($post->getTitle())->lower());
                // }

                if (empty($post->getSlug()) && !empty($post->getTitle())) {
                    $slug = $this->slugger->slug($post->getTitle())->lower();
                    $string = $slug->toString();
                    if (strlen($string) > 255) {
                        throw new \Exception('Generated slug exceeds the maximum length.');
                    }
                    $post->setSlug($string);
                }

from PostType.php file

and also in this code:

        // $names = array_filter(array_unique($this->trim(u($string)->split(','))));
        $names = array_filter(array_unique(array_map('trim', u($string)->split(','))));

from TagArrayToStringTransformer

fixed with chatGPT

just try to add a post , in a server with php 8.4 and add for your php files strict_types

<?php declare(strict_types=1);

and add for your php files strict_types

Well, if you modify the code, you have of course make sure to do it consistently. Simply enabling strict types is not enough as you also may have to adjust some calls.

I enabled strict_types in all php files

I understood that and that’s simply not something you can do blindly without checking if the code contained in that file needs to be adapted.

I am closing here as that’s not an issue of the demo code but how you deal with it. Thank you for understanding.
