A 502 is a bad gateway error. You can read more about it here. This means you're traversing a gateway or proxy server in order to get to the actual target server, and the response the gateway/proxy received from the target server was not correct.

Have you tried testing this with Postman?

Ok. This tells us it's likely an issue with the server you're trying to connect to. Is this a server within your own environment? If so, I'd suggest reaching out to your IT department or the owner of that server to see if they can review their logs to see what it thinks the issue is.

yes it worked.

There was an issue with the api headers given by them.

Thanks.
