Already I have spent a lot time to resolve the issue but not getting the actual reason. I have a issue during parsing the json, below is the my josn which i am trying to format.
ERROR: 757: unexpected token at '"{\"requestId\":\"2323423432\",\"bids\":\"[ {\\"adId\\":50000001, \\"bidNative\\":100,\\"clickPayload\\":\\"clickPayload-1\\", \\"impressionPayload\\":\\"236|458795|12345\\"}, {\\"adId\\":60000002, \\"bidNative\\":200,\\"clickPayload\\":\\"clickPayload-2\\", \\"impressionPayload\\":\\"236|458795|12345\\"}, {\\"adId\\":60000002, \\"bidNative\\":300,\\"clickPayload\\":\\"clickPayload-3\\", \\"impressionPayload\\":\\"236|458795|12345\\"}]\"}"'
actually wherever it shows 2 slashes there are actually 3, but i dont know why stack overflows editor shows like this.
