I think that on any error should be run the .catch branch.

If server return 404 - I am expecting an error, not complete. I.e. .catch, not .then:
imageToBase64("file_not_exist.png")
.then(
(response) => {
console.log(response); // PCFET0NUWVBF... - base64 of server 404 response
}
)
.catch( // no fired!
(error) => {
console.log('Error: '+error); //Exepection error....
}
)

ok, in browser you must setting the path, example:
imageToBase64("./file_not_exist.png").then(console.log).catch(console.log);OR
imageToBase64("https://yourdomain.com/images/JavaScript-logo.png").then(console.log).catch(console.log);In browser you always using URL.
Do you understood?
see ya.

Sorry for delay.
Ok, if file name begin from "http..." then the .catch are fired on 404. If not (even if the path present) - the .catch not fired on 404. Is it ok?

I tried access yours images and don't possible. So, this probably is a error in your server.
This can be a problem of path or url.
You can testing as example below:
imageToBase64("http://mediatheque.rsl.ru/image-to-base64/test/nodejs.png")
.then(
(response) => {
alert('2. This is responce ok too. Result are '+response.length+'bytes length.');
}
)
.catch(
(error) => {
alert('2. Error');
}
)from image-to-base64.

Sorry, I don't understand.
The right image url is: "http://mediatheque.rsl.ru/image-to-base64/test/nodejs.png"
The "http://mediatheque.rsl.ru/test/nodejs.png" - is a sample a bad url, this produce 404 server response.
By link above You can see code in action, and see alert number and message. Messages appear not in the order of numbers, of course.

No problem, my English is very bad.
Well,
This error occurs because this route (URL) that you try access don't exists in your application.
Your images they are inside path image-to-base64, understood?
I realized that you this using my images of example, do you need on your application put on all images and execute code with path.

Yes. My case is generate the image file name, and retrieve file by this name. If file exist - display img, if not - do something. I want only one request to server for it.
On this case I do not have way to check "File not exist" situation.
