Question
Publish to Robot Manager Failed.
We are getting "An item with the same key has already been added." in the Exception Information while deploying our code to Platform.
An item with the same key has already been added., Verbose Message: General Information

We tried to delete the entries from Robot Manager and Package Server and tried to deploy from Studio.
Got the same error message. "An item with the same key has already been added"
Did you perhaps make a copy of a prior project you have deployed? The projects are actually tracked by their project ID and not their name. If you created a project named X and deployed it and then made a copy of it, renamed it to Y and deployed it, you might see the same message.
This usually happens when you are publishing a version of a package you have already published. If you need to overwrite a version, delete it from both the package server and Robot Manager and then publish. If the version number can be changed, simply alter the version number in the startup project of your solution and publish again.
