Hi tried deploying on heroku but it always give me error while its intalling the node enigne can u help out

I installed this code on Amazon EC2 (along with Node and NPM) and opened port 5858 and 8080. I ran node server.js and got the following terminal message:

8080
blah blah

I then visited mysite:8080 which loaded normally. However, when I click on "Visualize Execution" nothing happens in the browser. The terminal displays a message [SourceExecution] : StdErr Debugger listening on port 6060.

Opening up port 6060 doesn't solve the problem. When I close the server in the terminal, I get a message in the browser "Server error (possibly due to memory/resource overload)..."

Is any additional setup needed to get the Javascript Debugger to work?

Feature request to consider:

When the slider has focus, press "j" (for jump), or another key, and follow that with a number.

That would teleport you to the line of code that corresponds to that number.

The difficulty is that multiple Frames-Objects pair images can belong to 1 line of code.

If it's possible, perhaps show a list of all the pairs.
The pairs could be shortened, compacted, and/or summarized to fit on the screen.
Maybe it just lists the step numbers that correspond to that line number.
Then, a person would be allowed to choose the Frames-Objects pair to skip to.

Or, just pick the earliest Frames-Objects pair that will appear from the current step.
That is, "what's the next step that will take me to this line of code?".

I have a motor disability, so keyboard accessibility is something that I seek.

(The request might be too much, but I still think that it would be pretty convenient 😃).

Thanks for the amazing program.
