No formatting

[eernstg]

DartPad seems to have stopped performing a formatting when the formatting button is clicked, or the keyboard shortcut is pressed.

What happened?

DartPad does not format as expected. It seems to occur with the 'main' channel, and not with others.

Steps to reproduce problem

Enter the following program (or anything that needs formatting) into the source code pane of DartPad, running in the 'main' channel:

void main() {
  var _ = switch (1) {
    1 => 0,
              _ => 1,
  };

    print( 'Hello!');
}

Click the formatting button (nothing happens) and press the keyboard shortcut (Command-S on this laptop -- again, nothing happens).

Additional info

DartPad shows this: "Based on Dart SDK 3.8.0-250.0.dev and Flutter SDK 3.31.0-1.0.pre.363."

Are you using any extensions/plugins that affect website behavior
(particularly those that affect iframes, such as ad blockers)? Nothing that should change the behavior of this website. Also, no extensions were installed or removed since the time where DartPad did format the code when requested.

Are there any warnings or errors in your browser's JavaScript console? No.

DartPad's output

Did DartPad print anything to the console pane? No.

Perhaps DartPad was just updated? Anyway, the issue is gone. Closing.

It looks like this behavior is being turned on and off every few minutes ... now I've seen the formatting working and not working several times.

Once, I got this message in the output pane:

Formatting issue: ClientException: Failed to fetch, uri=https://master.api.dartpad.dev/api/v3/format

and this one in the messages area of the source code pattern (at the bottom):

ClientException: Failed to fetch, uri=https://master.api.dartpad.dev/api/v3/analyze

Taking the same actions again, there are no messages, but also no formatting.
