editor.component.scss:17:100: ERROR: Unterminated string token – Angular + Scss


I am getting unterminated string token error in my angular application that uses scss as stringUrl.

@import "~bootstrap/scss/bootstrap";

.view-container, .module-row, .view, .view-inner-container {
    flex: 1;

.advanced-editor-wrapper {
    @extend .h-100;
    .advanced-editor-header {
        @extend .p-2, .d-flex, .align-items-center, .justify-content-between;
        border-bottom: 1px solid #333;
        h4 {
            @extend .d-inline, .m-0;
        .header-button {
            @extend .mr-2, .btn;
    .parent-flex-container {
        @extend  .p-2, .w-100, .h-100, .d-flex, .flex-column;
        .add-view {
            @extend .btn, .h-100, .m-1, .w-100, .d-flex, .flex-column, .align-items-center, .justify-content-center; 
            flex-basis: 50px;
            background-color: transparent !important;
            border: 2px dashed #2799A5;
            color: var(--body-color);
            transition: all 0.2s ease-in;
            border-radius: 5px;
            &:hover {
                background-color: #333 !important;
                border-color: var(--body-color);
            &.flex-row {
                flex-direction: row !important;
        .module-row-container {
            @extend  .d-flex, .flex-column, .h-100;
            .module-row {
                @extend  .d-flex, .flex-row, .mb-2;
                .view-container {
                    @extend .w-100, .d-flex, .flex-row;
                    .view-inner-container {
                        @extend  .d-flex, .flex-row;
                        .view {
                            @extend .m-1, .h-100, .position-relative, .d-flex, .flex-column, .align-items-center, .justify-content-center;
                            border-radius: 5px;
                            .view-header {
                                @extend .d-flex, .justify-content-between, .align-items-center, .p-2, .position-absolute, .w-100;
                                left: 0; 
                                top: 0;  
                                background-color: rgba(0,0,0,0.3);
                                h5 {
                                    @extend .m-0;
                                    font-family: 'Century Gothic'; 
                                    font-weight: 400; 
                                    font-size: 1rem;
                                button {
                                    @extend .p-0;


browserslist is included by @angular-devkit/build-angular, try running:

npx browserslist --update-db

This will update the caniuse-lite database with browsers, which helped me get rid of the ...17:100: ERROR: Unterminated string token error.

(the trick of setting minify: false did also work for me, but I rather have an up to date list of browsers, than turning off minifying)
