@rishabh-webkul could you please check laravel.log which is i posted?

Hello @rishabh-webkul

Thank you for your response.

We are currently using Bagisto version v2.4.x-dev.

Also, we have not implemented any customizations on our end; the installation is completely default.

Thanks.

Hello @divya

Can you share the logs from laravel.log file to debug the issue more at our end.

Usually this error "Unexpected non-iterable value for to-many relation" in Bagisto Swagger occurs when API Platform tries to serialize a relationship field (like images, categories, or variants) that should return an array/collection, but instead returns null or a single object.

Regards

This happens because Bagisto expects a default channel before most services boot. Easiest fix is to run the initial migration and seed in isolation by temporarily disabling the API package or commenting the channel call in Core.php, then run php artisan migrate --seed to recreate the default channel, and restore the code after.
