I get a blank page in preview but no errors in output

[red8888]

The autocomplete and intellisense features appear to be working correctly from what I can tell, its just preview that is not.

I have debug turned on.

This is what I see in the output and the preview pane is totally blank

I just saw your other comments...

With the version of esbonio you are using the port number is chosen dynamically and there's unfortunately, no option to configure it. I do not have much experience with dev containers... (I've never managed to get them to work :sweat_smile:), but it should be possible to configure VSCode to forward the port that should be written somewhere in the debug logs ([client] Result is {"port": 1234})

Another option is to try the pre-release version of the extension (v0.92.1). Full disclosure, the version of esbonio it uses is currently missing a lot of features compared with the mainline version, however, it does have a much improved preview engine, which includes the ability to force esbonio to use known port numbers.

In which case you will need to set both esbonio.preview.wsPort and esbonio.preview.httpPort options

@alcarney hey just saw this! Yeah I confirmed setting the port manually works!

Just curious you know what settings pre-release is missing broadly speaking?

[red8888]

Im also wondering why vscode's "remote.autoForwardPorts" isn't working here. Maybe because the ports aren't opened when the process is started initially?

[red8888]

Ah ok the following actually works at the expense of potentially breaking stuff.

                "remote.autoForwardPorts": true,
                "remote.autoForwardPortsSource": "process"

I did have vscode pop a message about how a large amount of ports had been opened:

But with this setting when I open the preview pane it spins up that port and I see vscode catch it.

Just curious you know what settings pre-release is missing broadly speaking?

Settings wise... I can't think of anything that's missing - but a lot has changed. For example, there's no longer the esbonio.sphinx.{build,conf,src,doctree}Dir etc settings to control Sphinx. There's just a single esbonio.sphinx.buildCommand setting where you give it your sphinx-build command.

There was also a few options around how esbonio gets updated, but since esbonio is now bundled with the pre-release version of the extension, they're no longer relevant and have been removed.

Side note: The docs you linked to in the other thread, despite saying it was the release version, it's in fact the pre-release version of the docs! :man_facepalming: If you want the documentation for the stable version you can find it here

Im also wondering why vscode's "remote.autoForwardPorts" isn't working here...

I wonder if there's an API the extension can implement to help with this.... :thinking:

Glad to hear that it sounds like you got it working though!

[red8888]

Gonna close because I got it working for now.

I had the same issue, got it working with Esbonio pre-release version and specifying esbonio.preview.httpPort in the settings.

EDIT: Now I get

[Error - 15:05:55] Request workspace/executeCommand failed.
  Message: OSError: [Errno 98] Address already in use
