Description:

Return value of Spatie\Once\Backtrace::getObject() must be an instance of Spatie\Once\mixed, instance of Laravel\Nova\Http\Requests\NovaRequest returned

Detailed steps to reproduce the issue on a fresh Nova installation:

[FaridAghili]

This happened to me when I was developing on my local machine with PHP 8 installed, and deployed the project to shared hosting which had PHP 7.4 installed.
Notice that, I copied whole Laravel project, including vendor folder to remote host and didn't run composer install on the remote host.

In fact, on my local machine spatie/once v3 got installed by composer (which requires PHP 8), and PHP 8 wasn't available on my hosting.

If you're doing the same, I suggest to install PHP 7.* on your local machine, run composer update, then deploy to server.

@FaridAghili thanks a lot

I can confirm that this issue appears on php 7.4, but not on php 8.0.

I have latest versions of Laravel and Nova.

In order to reproduce just install empty Laravel project from scratch and add Nova via Composer.

Hope it helps.

This error happen when you try to use spatie/once v3 on a php 7.4 environment. (It happened with me too)

As pointed in v3 release: https://github.com/spatie/once/releases/tag/3.0.0
The v2 drop support for php 7.

So the options are:

• Upgrade to php 8 OR
• Use spatie/once v2.x

Look at your composer.json if you dont manually add spatie/once ^3.x.
Laravel nova already has the dependency as "spatie/once": "^1.1|^2.0|^3.0", , so you don't need to add it to your composer file.

If in your local environment you use php 8 the composer will install spatie/once v3, but if deploy to a server with php 7 it will lead to a error. In this case, just add to you composer.json: "spatie/once": "^2.0"
