The image is not saved in the database or in the public

[danielreales7]

I am having a problem when I save an image to the database:

I don't have any errors. Only when I call $image->getUrl()

TypeError: Return value of Spatie\MediaLibrary\Support\PathGenerator\DefaultPathGenerator::getBasePath() must be of the type string, null returned in file C:\xampp\htdocs\aldanux-web\vendor\spatie\laravel-medialibrary\src\Support\PathGenerator\DefaultPathGenerator.php on line 38

Post Model has:

How can I know why it is not storing anything in the database?

Thank you so much for your help!

If for example I upload the file directly through Storage it will upload it correctly.
