solved changing this

app/design/frontend/Altravista/bookshop/requirejs-config.js

 var config = {
    deps: [
        'js/custom'
    ],
    paths: {
        'popper': 'js/bootstrap/popper.min',
        'bootstrap': 'js/bootstrap/bootstrap.min'
    },
    shim: {
        'popper': {
            'deps': ['jquery', 'bootstrap'],
            'exports': 'Popper'
        },
        'bootstrap': {
            'deps': ['jquery', 'popper']
        }
    }
};

with

var config = {
    deps: [
        'js/custom'
    ],
    paths: {
        'popper': 'js/bootstrap/popper.min',
        'bootstrap': 'js/bootstrap/bootstrap.min'
    },
    shim: {
        'popper': {
            'deps': ['jquery'],
            'exports': 'Popper'
        },
        'bootstrap': {
            'deps': ['jquery', 'popper']
        }
    }
};

remove bootstrap from popper shim
