@pjninnim FYI I'm also having the same problem.

[rodrigovaras]

Can you provide more context which language is affected? Did the error happen on the host side? Are you sharing a workspace when the error happen?

[pjninnim]

@rodrigovaras Trying to just run the debugger with the extension enabled gives the error when debugging a node/javascript. Disable the live share extension and debugger loads correctly. Only started happening from Tuesday, this week with one of the vscode updates. If was all perfect before that.

My launch code is below if it helps:

We will investigate on our side. FYI, we recently changed the way we host debug session on live share and i presume all this type of errors will go away, but the current version enabled this only for experimental option. We will soon migrate to enable the new mechanism by default

[srivatsn]

@pjninnim can you see if setting liveshare.features = experimental fixes the issue for you?

[pjninnim]

@srivatsn I just tried all 3 options... default, stable and experimental (what I has set by default) and the error occurs when using all 3 choices.

[srivatsn]

Thanks. That's good to know. We'll look into this. /cc @jramsay

[jramsay]

Thanks for the info @pjninnim! I've tested it out and can also repro the issue (on Insiders only - Stable is fine) when liveshare.features is set to experimental.

Can you try setting your user options explicitly to "stable" again? After you do this you'll have to close and reopen VS Code Insiders for this setting to be applied. Can you let me know if this resolves the issue?

[pjninnim]

@jramsay Thanks. Yes setting it to 'stable' then closing and reopening did resolve the issue.

[jramsay]

Glad to hear! If you update VS Code Insiders you should be able to switch back to VS Live Share _experimental_. The issue has been resolved in their latest update.

[pjninnim]

@jramsay Thanks. I can confirm the latest update has resolved the issue.

[pjninnim]

@jramsay As I said before it has resolved the issue but I've noticed it has only solved it for initial start / stop. If you start up the debugger, then restart it you receive this:
