Hi,
Handling endpoints in the node server and constantly getting
<Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client>
Error appears in the row having 200. I would think that this error shouldn't appear as I'm checking that header has not yet been sent..
else if (res.setHeader !== true) {
res.status(200).json({ message: getLicenseResp });
}
What I'm not getting 🙂 ?

What is res.setHeader !== true code checking? Should that be res.headersSent? And is there a reason that you'd want to check if the headers were already sent while in the route code anyway? I can't imagine a scenario where you would need to check that.

With res.headersSent you are likely on the spot :), not getting why I didn't see that. I want to ensure that the server doesn't crash as it now seems to do so that's the whole point of checking.
Thx from the info !👍

Have you been able to resolve the issue?
If not, then add a return keyword behind your res.
One of the causes of that error is that sending a response doesn't stop the execution of the codes after it, so in other to stop such execution, you have to add a return keyword behind or below it.

Thx from the advice, I was under the impression that a return is not required. In case there are still issues, I will try this.
