Placing bet unexpected error

[pawlo16]

I'm trying to place a simple bet on the actual market with a valid option.

{
	"jsonrpc":"2.0",
	"method":"SportsAPING/v1.0/placeOrders",
	"params":{
		"customerRef":"",
		"instructions":[{
				"limitOrder":{
					"persistenceType":"LAPSE",
					"price":1000,
					"size":4
				},
				"orderType":"LIMIT",
				"selectionId":2909657,
				"side":"BACK"
			}
		],
		"marketId":"115097009"
	}
}

But in return I get the following error.

{
	"error":{
		"code":-32099,
		"data":{
			"APINGException":{
				"errorCode":"UNEXPECTED_ERROR",
				"errorDetails":"",
				"requestUUID":"prdang-288287-08111209-00079971d0"
			},
			"exceptionname":"APINGException"
		},
		"message":"ANGX-0006"
	},
	"jsonrpc":"2.0"
}

What am I doing wrong? Thanks in advance for your response

At a guess I would say you either have to supply a customer reference (not a blank string), or not supply one at all.

O, I tried to call this service without "customer reference" and with not empty value of "customer reference". As a result, i have got the same answer, unfortunately.

You have provided a bad marketid. it should start with "1."
if uk bettting and "2." if australian.

Thank you very much, it really works. Probably the documentation says about a form specifying identifiers market, but I did not meet. But at least we could expect а more informative exception rather than UNEXPECTED_ERROR
