Laravel: array_merge(): Argument #2 is not an array error

Question

Exceptions started to appear in all views, and when I try to run composer update, it always ends up with

{\"error\":{\"type\":\"ErrorException\",\"m         


        

Answer 1

Sometimes only deleting app/storage/meta/services.json and run composer update doesn't solve the ERROR: array_merge(): Argument #2 is not an array error. At least in my case, it didn't.

Most of the time it happens when you're screwing up the bootstrap/cache/services.json file. And running composer update will not generate services.json file.

To generate the services.json file, you need to delete the previous bootstrap/cache/services.json file and run php artisan serve. Then it'll generate a fresh services.json` file.

Hope it helps to someone!

Answer 2

I had similar problem with a fresh install.

I solved it like this: Removed bootsrap/cache/**services.php** and then i surfed to the website with browser, it generated a new services.php and then it worked.

Answer 3

Just a composer update worked for me.

Answer 4

You probably just forgot to put compact('var') as the second return view argument

return view("path.to.view", compact ('var'))

Answer 5

After a lot of searching and exploring each file in the 'app' folder, it appears that one file was corrupt

Delete app/storage/meta/services.json and re-run composer update and this should solve it.

Answer 6

1. delete bootstrap folder
2. git reset --hard
3. composer install
