Creating API Map for WRS endpoints is painfully slow as Firefox takes all available memory. Only after API tree is fully collapsed it becomes somewhat navigatable. Is this a bug or 'normal' behavior? Is there any other way of defining API Maps e.g. in XML and through importing?
How many endpoints are in the tree? Where is the server located that you are trying to connect to? Is it on a different network? Have you tried it under other browsers?
It's a standard WRS endpoint (/v5/ProdMgmt/Parts GET) and the Windchill is on another server, but the same physical location. When I invoke the query with Postman or Swagger it executes normally. Part definition in our organisation is on the other hand quite complex and this is what I believe is the bottleneck for ThingWorx. We tried defining API Maps in Edge (chromium) but it is the same story.
It sounds like a case will be needed for this. If you have a support contract, please send me a private message with your PTC Support email address and I will be happy to open the case on your behalf.
It is possible to accomplish but you have to keep collapsing tree until it becomes more manageable and responsive. Takes ridiculous 15 minutes per mapping and about 10 gb of memory.
You advised you are running ThingWorx 9.1.0. What versions are you running of the other components? We need to confirm that all components are compatible.
If we're unable to determine anything further in the community, we'll need to open a case in order to do a deeper dive.
