How can I redirect a Blogger blog to another blog

How can I redirect a Blogger blog to another blog - If a page has internal and external outgoing links to redirecting URLs, it’s returning 3xx (301, 302, etc.) HTTP status codes standing for redirection. This issue means that the page does not exist on a permanent or temporary basis. It appears on most of the popular web browsers, usually caused by a misconfigured website. However, there are some steps you can take to ensure the issue isn’t on your side. You can find more details about redirecting URLs by reading the Google Search Central overview. In this article, we’ll go over how you can fix the How can I redirect a Blogger blog to another blog error on your web browser. Problem :

I have a blogger blog with its own domain (I'll call it www.example.com); that's to say: this site used to be a www.example.blogspot.com and I purchased a name domain later; I can continue to manage settings from the Blogger control panel.

Now, another webmaster will write my name on a page of her website and I'd like her to insert a hyperlink to let users be redirected to mine (when they click on my name).
BUT I don't want to provide the URL of my website because I'd like to be able to immediately stop redirecting if I change idea (in case I no longer want my website to be associated to others).

This is the reason why I created another blogger blog (I'll call it www.bloggerblog2.blogspot.com) and I'm trying to use this new address to redirect to www.example.com.
I cant't do that from the settings of Blogger because I get an error. More specifically, I'm on Settings -> Search preferences -> Custom Redirects -> New Redirects. At this point I write the two URL addresses and save but I get the error message

The source and destination values cannot be empty or more than 256
characters and must start with /.

I wonder why I'm getting this error?
May I handle this by editing the HTML code of the blog (and how)?

Solution :

You're getting this error because Blogger only allows redirects inside your blog.

For your purpose, You could buy another domain name and redirect it to your blog or use a url minifyer to hide your example.com in the links.
