Laravel 5.8: Migrations Foreign key constraint is incorrectly formed

I created two tables and in the second one I set up a foreign key. When I call the comand php artisan migrate I get following error:

Foreign key constraint is incorrectly formed

The first table name is members and the second partners

$table->integer('member_id')->unsigned();
$table->foreign('member_id')->on('members')->references('id')->onDelete('cascade')->onUpdate('cascade');

$table->integer('member_id')->unsigned();

change as

$table->bigInteger('member_id')->unsigned();

becouse laravel use as default bigIncrement for id columns in migration files.

First of all since Laravel 5.8 all id are bigintegers

However since they are also unsinged you can do:

$table->unsignedBigInteger('member_id');

For the second line you might want to change the order:

$table->foreign('member_id')->references('id')->on('members')->onDelete('cascade')->onUpdate('cascade');

Do note that the members table should be created first before you can reference a key of it.

Your members table should be created before your current table
or maybe your memers id field has different type than your current table
please post your migration files
