Can you paste your source code?

[harishandroid]

const realtor = require('realtorca');

let opts = {
CultureId:1,
ApplicationId:1,
PropertySearchTypeId:1,
ReferenceNumber:'N4615865'

};

console.log( realtor.buildUrl(opts) );
//https://www.realtor.ca/Residential/Map.aspx#LongitudeMin=-79.6758985519409&LongitudeMax=-79.6079635620117&LatitudeMin=43.57601549736786&LatitudeMax=43.602250137362276&PriceMin=100000&PriceMax=425000

realtor.post(opts)
.then(data => {
//json response
console.log(data);
})
.catch(err => {
console.log(err);
});

please help me..

[harishandroid]

it was working fine for long time. today only i got issue

[Froren]

I saw the same error when I was testing as well. It seems to have gone away now, can you confirm?

If it comes back I think I'll have ways to tinker with it and see what I can come up with to address it. Let me know if it's still an issue now or in the future.

[harishandroid]

now it is working fine. i have installed node js on two systems . two systems shows same error and i have uninstalled in one system and reinstalled node js and now it is working fine in two systems.
i think because of ip issues i dont know for sure. But after uninstalling and reinstalling in one system it is working fine.

What version of Node are you using? I'm using v10.14.2 and getting the error with reference numbers also.

[stuartathompson]

This is an IP problem. I had the same issue, tried updating Node, same issue. Logged into my VPN and it worked.

While I was tinkering with this, I found that adding the some cookies with the request seemed to also fix the issue. Specifically, the ones prefixed with nlbi or incap_ses that you can find while making requests on realtor.ca.

I can see that the page also makes requests to an endpoint, https://www.realtor.ca/e8469ba99880590089b6cb783b503a90, which seems to be retrieving a possibly related token value.

Since it's a transient issue, I feel like it's just being experimented with (if at all), but I'm interested to see where this goes.

status code 403 is there any solution
