I have the same problem, the bug reported here before, I was hoping this will be fixed in this version but still exist! even on v.2.3.5
actually, I don’t know it maybe is the bad loading of SDK or maybe a conflict between packages, but in the previous version of my project with SDK v(1.9.6), this error was not thrown.
Problem is on zoomus-websdk.umd.min.js file Putting Array.prototype. uniquelize || before Object.defineProperty(Array.prototype, "uniquelize" will fix this but I had to do this change every time I install any package on my project.
