Why can't I read properties from a JSON cookie in express, when I see them in the console?

Question

I have the following code in express middleware...

const cert = req.cookies.Thing
console.log(` cookie is`, cert);
console.log("We got a cookie! "+ cert.property_a);

but the console shows...

 cookie is {"property_a":"blah","scope":"thing"}
 We got a cookie! undefined

If it is there, why can't I access the property? I even tried the JSON.parse(JSON.stringify) hack but no luck.

This may be helpful, if the issue is because of lazy resolving like promise.

Can't access object property, even though it exists. Returns undefined

Looks like the answer is although it displays like a JSON object it is a string. I solved this by using Object.values. This showed me a bunch of commas and I realized it wasn't getting parsed as JSON. Still trying to figure that last part out.

Object.values(cert)
