We have tried with the sample https://github.com/OfficeDev/Microsoft-Teams-Samples/blob/main/samples/graph-change-notification/nodejs/ and we are not getting incorrect status. It's only sending request when we are changing it or automatically change by some Team's Activity.
Could you please try sending status as 202. Whenever you are getting that request successfully.?
console.log("api is working");
if (req.body && req.body.value && req.body.value.length > 0) {
req.body.value.map(i => {
console.log(i.resourceData)
})
res.sendStatus(202);
}
Please give it a try and let us know if you are still facing it.
Thanks,
Hunaid Hanfee
