What happened?

I haven't tried to reproduce it, but I got this error in a production app:

GraphqlResponseError: Request failed due to following response errors:
 - Content already exists in this project

I assume it occurs when trying to add an issue or pull requse to a project that was already added, but I thought that theGraphQL API is already handling that gracefully. Maybe there is some racing condition?

Would you be interested in contributing a fix?
