Vscode debug error for Deno application: Could not connect to debug target at

Question

I am following deno course on Pluralsight (Deno: Getting Started). I am on debugging module. When I try to start the debugger, I am getting this error message on vscode:

This is my launch settings:

{ "name": "Launch Deno", "request": "launch", "type": "pwa-node", "program": "affiliate_data_server.ts", "cwd": "${workspaceFolder}", "runtimeExecutable": "deno", "runtimeArgs": [ "run", "--inspect", "--allow-all" ], "attachSimplePort": 8888 },

Debug console gives only this output:

C:\Users\kara\.deno\bin\deno.exe run --inspect --allow-all affiliate_data_server.ts

Sometimes, when I click to cancel, application still listens on the port, so i have to kill the process manually.

When i try this config instead;

{ "name": "Node Deno", "type": "node", "request": "launch", "cwd": "${workspaceFolder}", "runtimeExecutable": "deno", "runtimeArgs": ["run", "--inspect", "-A", "affiliate_data_server.ts"], "port": 9229 },

It starts the server but breakpoints are not working.

What would be the solution?

There's a discussion around this at github.com/denoland/vscode_deno/issues/384 — jsejcksn

I have solved the issue by downgrading the Deno to version 1.6.1 with

deno upgrade --version 1.6.1

You can use --inspect-brk instead of --inspect so it will break on the first line of the program.
