I Solved the error by making some changes in the migration. Incase anybody needs help:

    `Schema::create($voucherTable, function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('code', 32)->unique();
        $table->morphs('model');
        $table->text('data')->nullable();
        $table->timestamp('expires_at')->nullable();
        $table->timestamps();
    });`

  `  Schema::create($pivotTable, function (Blueprint $table) use ($voucherTable) {
        $table->bigIncrements('id');
        $table->bigInteger('user_id', false, true);
        $table->bigInteger('voucher_id', false, true);
        $table->timestamp('redeemed_at');

        $table->foreign('user_id')->references('id')->on('users');
        $table->foreign('voucher_id')->references('id')->on($voucherTable);
    });
