I followed this tutorial to add lodash + moment with locale to my project: https://blogs.sap.com/2017/04/30/how-to-include-third-party-libraries-modules-in-sapui5/.
Code checking is enable and found me, 50 Errors and 1500 Warnings on the "lodash.js" and "moment-with-locales.js" files.
After searching how to disable the code checking via Projects Settings > Code Checking i didn't find anything.
I'm on SAP Web IDE Full-Stack Version: 190704.
The project is a SAPUI5 Application from Template.
If you have an idea.
