            accountId: "1234", siteId: "1234", zoneId: "1001"

        }
    }, {
        bidder: 'rubicon', params: {
            accountId: "1234", siteId: "9876", // Note: <-- this siteId doesn't match the other two bids, so a second request is sent for bids with that 'siteId' value
            zoneId: "1003"
        }
    }]
}];

@idettman There's a merge conflict. Can you resolve it?

[mike-chowla]

The test parameters for validating bids are missing closing brackets under parameters structure. All three have the missing bracket

I'm not getting bids back with them either

Please fix the merge conflict.

This change is large enough that it should be validated with working test parameters but I'm not getting bids back on the test params

I did not see any code issues

LGTM

@mike-chowla regarding your comment on working test params: unfortunately our endpoint will not be able to handle SRA requests until after the Prebid release, we're merging with a feature that is off by default, so it shouldn't cause issues with existing since it has to be enabled though config. We have tested internally with integration tests so we're confident the code change isn't a breaking change.
