Chained paiments get Internal Error with http 200 response

[duzyiod]

I trying to get chained request on live environment.

Sandbox environment works well. But when i trying to do live request with live credentials i get 200 http response, but there is an error message "Internal Error". What does this mean?

{
	"responseEnvelope":{
		"timestamp":"2018-04-17T04:43:39.023-07:00",
		"ack":"Failure",
		"correlationId":"2e084df7e4244",
		"build":"45798054"
	},
	"error":[
		{
			"errorId":"520002",
			"domain":"PLATFORM",
			"subdomain":"Application",
			"severity":"Error",
			"category":"Application",
			"message":"Internal Error"
		}
	]
}

Credentials should work with chained payments.
