Hello, I am building an app to enable us to check our user's email directly from our dashboard, I have successfully accessed the Messages / View API without problem, but when I tried to use the Messages / Search API I encountered a 500 Internal Server Error, 

For the parameters I only sent the searchKey parameter.

Here is the error response:

{"status":{"code":500,"description":"Internal Error"},"data":{}}

Thanks in advance
