php artisan doesnt work [ErrorException] Undefined offset: 0 in laravel 5.1

Could you post the complet stack trace of your error ?

You can have it by running this command from your root folder :

tail -f storage/logs/laravel.log -n300

It's often an issue in your routes.php file from my experience.

thanks for reply

error happens here, in this method

/** * Get an item at a given offset. * * @param mixed $key * @return mixed */

public function offsetGet($key)

{

   //here

    return $this->items[$key];

}

Hi,

I am also getting this error,

vendor/laravel/framework/src/Illuminate/Support/Collection.php Undefined offset: 0

I have tried - view:clear, route:cache, route:clear, cache:clear then updated composer and run dump-autoload

but same error

Can you please help me out here. Thanks

The problem probably lies in the data in the collection, not the Collection class itself.

We can't help without any useful information (code or a stack trace). In this case I think a stack trace would be most useful to point to the correct file/line.

Maybe you could read the trace yourself to see where it points to your code. From there you could debug your data/code.

Whats on FrontEndApiController.php, line 517?

Line 516 - $Userauth = Members::where('phone', '=', $phonenumber)->get(); 517- if (strtoupper($Userauth[0]->language)

@satishshinde you don't appear to allow for your query returning no results?

use firstOrFail and then you will only get one result and also not need to access the [0] element of the collection

@mikevrind Thanks a lot, I figured out the issue.
