无法对来自SQL Server的数据执行JSON.parse

Question

I have a query that gets data from SQL Server, and in one of the fields we are storing JSON as a varchar(max) . The issue is that when I try to get the data out in my Node app and do a JSON.parse , it's not working. Here's what I've tried:

console.log(data.attr);
    // "{ firstName: 'Preston', lastName: 'Lamb' }"
JSON.parse(data.attr) 
    // Invalid expression: unexpected end of input (get this on one item)
    // invalid expression: unexpected token f in json at position 2 (and this on the other)
newJsonStr = JSON.stringify(data.attr)
    // ""{ firstName: 'Preston', lastName: 'Lamb' }""
newJson = JSON.parse(newJsonStr)
    // "{ firstName: 'Preston', lastName: 'Lamb' }"

None of this is really complicated stuff...it should be easy to JSON.parse and/or JSON.stringify, but it doesn't work. Any ideas at all?

What the other commentator meant by it's not JSON is that your keys need to be wrapped in quotes to be parsed as JSON.

JSON Spec - does the key have to be surrounded with quotes?
