After my last interaction with John Santos I thought we have cleared a problem with GoJS libraries, but we did not.
Today the project that seemed to be fine for few days again poped up same errors. I opened another project and got the same errors.
I opened APP folder deleted all files, removed TMP files as well, restarted SC and regenerated project and BUM !!! GoJS errors are back.
At least on two projects that I do not use GoJS at all, I gett GoJS related errors.
Net make needs to adress this problem. I cannot work like this
