[BUG] Call to a member function toCodeString() on null about laravel-scout-elasticsearch HOT 5 CLOSED

We had the same error today. The problem was that we used anonymous classes in our code base. By replacing them with generic new stdClass() we fixed the problem. This is quite an ugly solution, but it works.

I hope this helps anyone having the same error.

@Ecsodikas thanks for sharing yours findings. don't remember details but yes anonymous classes not supported to be able to search by multiple models as I remember.

Hey. Feel free to send a PR

from laravel-scout-elasticsearch.

The error occurs because for some class nodes, the namespacedName property is null, indicating that these class nodes do not have a fully qualified name. This could happen if the class does not have a namespace defined, or if there is an issue with the way the AST is generated or traversed.

Could you provide more info about file on which the error occured?

Issue: Error: Call to a member function toCodeString() on null

Description

I am encountering an issue with the matchish/laravel-scout-elasticsearch package when running the php artisan scout:import command. The error message I receive is:

Error: Call to a member function toCodeString() on null

This error occurs at the following line of code in the SearchableListFactory.php file:

return $node->namespacedName->toCodeString();

From my understanding, it seems that namespacedName is null for some $node objects, and therefore, calling toCodeString() on it results in an error.

Steps to reproduce the issue

1. Run the php artisan scout:import command.

Expected Result

The command should execute successfully, without any errors.

Actual Result

I get the error Error: Call to a member function toCodeString() on null.

Additional Information

• Laravel version: 9.52
• PHP version: 8.1
• matchish/laravel-scout-elasticsearch package version: ^7.2

I have tried re-installing the package, moving non-class PHP files to a different location, and updating the composer.json file's autoload files array. Additionally, I have checked all models in the App namespace, and all of them have the class defined and no files are missing the class definition. However, none of these steps have resolved the issue.
