Neo4J:Migrate:Rollback not working at all

[axelthat]

When I try to run php artisan neo4j:migrate:rollback or php artisan neo4j:migrate:refresh, it gives me the following error:

Vinelab\NeoEloquent\QueryException  : ParameterNotFoundException: Expected parameter(s): migration, migration

How can I fix this?

Please add the version of NE that you are using (preferably from your composer.lock file). And more details about the migration code that you attempt to rollback (all a similar fictitious example if you'd rather preserve confidentiality).

Hi @Mulkave ! I am using v1.4.6 !

[axelthat]

Here's the migration code which I attempted to rollback:

<?php

use Vinelab\NeoEloquent\Schema\Blueprint;
use Vinelab\NeoEloquent\Migrations\Migration;

class CreateUsersMainLabel extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Neo4jSchema::label('users_main', function(Blueprint $label)
        {
            $label->index('fname');
            $label->index('lname');
            $label->unique('email');
            $label->index('password');
            $label->index('old_password');
            $label->index('joined');
            $label->index('dob_year');
            $label->index('dob_month');
            $label->index('dob_day');
            $label->index('gender');
            $label->index('country');
            $label->index('active_status');
            $label->index('last_active_status');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Neo4jSchema::dropIfExists('users_main');
    }

}

Hey SanjayBanjade,

you should upgrade to version v1.4.7. This was fixed in this release.
