I have been using this line to prevent experiments won't accidentally sent to the public server (I have my custom self-hosted server)
Task.set_credentials("PLACEHOLDER", "PLACEHOLDER","PLACEHOLDER")

However, when I upgraded from 0.17.5 -> > 1.0.0. Weird stuff happen.
Since upgrade from v0.17.5 -> > 1.0.0, it has issue replacing the credentials.

Expected Behavior:

Conf should replace the "PLACEHOLDER" is the conf file exist. Else it should fails the experiment.

What happened:

The experiment fail when conf file exists. I can guarantee the conf file is valid, since if I remove
Task.set_credentials("PLACEHOLDER", "PLACEHOLDER","PLACEHOLDER")The experiment was init sucessfully and send to my custom domain, this indicate the conf file is read, but fail to replace credentials.
