We recently created an API Key and then afterwards deleted it.

After that, we are no longer able to create new API keys, whenever we try, after keying in the api key details and try to save, it will throw this error.

Error

Object reference not set to an instance of an object.

Any ideas on how this can be resolved?

Thanks
