First attempts with remote-plugin sample. HTTP Error 405- Get is not supported for url: https:///api/ui/htmlClientSdk.js

Hi

I've been trying to work with the Remote Plug-in Sample found in the vCenter 6.7U1 SDK.

I am able to build the sample, start it and register it in my Windows vCenter 6.7U1.

The plug-in is deployed, and I can see it in the html client.  But when I click on the Global View, the page is empty. In my Browser Console, I see the error above.

Can some one tell me how to handle this?  Did I do something wrong?

thanks for the help
