Can you attach an example of how you requested the data (blocking out the API key value with ##### or other characters)?

Hey!
I've opened this GH issue for the exception been seen. But for this case the issue can be seen in this error log "History calls for IEX require an API key.", you need to set the "iex-cloud-api-key" in you 'bin\Debug\config.json', history requests should work correctly since they directly use a web client, unaffected by issue #4815.
Hope this solves the issue!
