"Error! Could not connect! See error log."

Anybody solved that issue? i'm getting the same error
log shows -
Error: array_key_exists(): Argument #2 ($array) must be of type array, Stripe\Util\CaseInsensitiveArray given
{"object":"Account","method":"retrieve","args":[]}

Looks like some sensitive account details are omitted from the Stripe response if you're making an API call from test mode.
The "Test Stripe Connection" calls the /account endpoint and looks for an email address, which is one of those sensitive values.
