I’m not sure if this was a thing in the previous version (I don’t think so) but for future reference when changing the user id on the user table to a UUID there’s and extra step now.

The error I encountered.

Invalid text representation: 7 ERROR:  invalid input syntax for type bigint: '...' Connection: pgsql, SQL: update "sessions" set "payload"

In the file 0001_01_01_000000_create_users_table.php the user id column and the session foreignid column need to be updated to work with uuid’s, otherwise it will error when trying to register due to it not being a bigint anymore.

So change the user id to $table->uuid('id)

Schema::create('users', function (Blueprint $table) {
    $table->uuid('id');
    $table->string('name');
    $table->string('email')->unique();
    $table->timestamp('email_verified_at')->nullable();
    $table->string('password');
    $table->rememberToken();
    $table->timestamps();
});

and then in the same file change the sessions table foreignId to the following $table->foreignUuid('user_id')->nullable()->index()

Schema::create('sessions', function (Blueprint $table) {
    $table->string('id')->primary();
    $table->foreignUuid('user_id')->nullable()->index();
    $table->string('ip_address', 45)->nullable();
    $table->text('user_agent')->nullable();
    $table->longText('payload');
    $table->integer('last_activity')->index();
});
