How to fix the incompatible issue on M2.3.1?

Issue: 

We have installed Fast Order v1.3.3 for Magento at the clean installation at M2.3.1 version and the extension has errors.

Solution:

The issue is caused due to the fact that the current version is not compatible with M2.3.1 at this time.

The class jquery-ui-modules/widget is only on M2.3.5 and higher versions.

We would like to give the hot-fix solution to solve this issue.

Step 1: Edit these files:

app/code/Bss/FastOrder/view/frontend/web/js/configurable.js

app/code/Bss/FastOrder/view/frontend/web/js/custom/downloadable.js

app/code/Bss/FastOrder/view/frontend/web/js/custom/grouped.js

app/code/Bss/FastOrder/view/frontend/web/js/custom/price/option.js

app/code/Bss/FastOrder/view/frontend/web/js/downloadable.js

app/code/Bss/FastOrder/view/frontend/web/js/fastorder-swatch.js

app/code/Bss/FastOrder/view/frontend/web/js/fastorder.js

app/code/Bss/FastOrder/view/frontend/web/js/grouped.js

app/code/Bss/FastOrder/view/frontend/web/js/integrate/configurable-grid-view.js

app/code/Bss/FastOrder/view/frontend/web/js/integrate/request-for-quote.js

app/code/Bss/FastOrder/view/frontend/web/js/price-options.js

app/code/Bss/FastOrder/view/frontend/web/js/product/view/option.js

app/code/Bss/FastOrder/view/frontend/web/js/select-option.js

Step 2: Apply the files and the site and flush the cache.
