Uses deprecated APIs 1 warning found Browser errors were logged to the console

I have added an image of the WordPress site where I am facing these two issues which are becoming a hurdle in my site to optimize for best practices. I tried to find its solution but got no understanding of how to do that in my website of WordPress.
Uses deprecated APIs 1 warning found
Browser errors were logged to the console
Screenshot from Chrome inbuilt dev tool
I have found the solution by removing this policy from htaccess file. It's an HTTP header. You can check your website HTTP headers.
Header set Expect-CT enforce,max-age=2592000,report-uri="https://example.com/"
here is some help on this issue I believe.

IIS error 403 not logged and showing unknown error page

When I try to access a page on my IIS web I get an error 403. The error is not logged to the log file and the error page shown is not the one that's defined in the config.
That's the content of the error page:
<html><head><title>403 Forbidden</title></head><body>Access denied</body>
Can anyone help me to find this error page and get the error logged?
The 403 Forbidden error is an HTTP status code that means that accessing the page or directory you were trying to reach is absolutely forbidden for some reason.
To resolve this issue, you need to enable directory browsing for your application. To enable directory browsing on IIS, check out the steps from this Microsoft document.
If you still can’t solve the problem, you can use failed request tracking to view detailed error information.

/CMSPages/PortalTemplate.aspx throws 404 errors but site still works fine

I have a situation here, on iis logs I see the /CMSPages/PortalTemplate.aspx causing 404 errors but the requests are still fulfilled.
The question that I have is how do I stop these 404 errors from being logged since the website still works. I only want to see the real 404 erros which occur when the request URL is invalid
I am using the Portal Engine approach
In the IIS log, find out what the parameters after the /CMSPages/PortalTemplate.aspx causing the 404. You may be able to see these 404 errors in the Kentico Event Log as well. The majority of the requests to deliver page content goes through the /CMSPages/PortalTemplate.aspx page which is why you're seeing it in the IIS logs.
Once you find the record which has the 404 info, you should be able to find the path to the file and resolve it.
Check your network tab in your favorite browser. Usually there is a favicon or woff font not being served.

How to customize 502 page in Node.Js?

When I try to access my URL running a Node.js app, when the app not running, the page shows
502 – Bad Gateway
The page you requested is currently unavailable. Please try again
later.
If you are the website owner, please see Error: 502 Bad Gateway
documentation for more information and possible steps to resolve the
problem.

Is there a way to customize what shows on this page?
This error isn't caused by node.js; it is caused by a proxy between you and node.js. This may mean that your server isn't running. Try contacting webfaction.
