Breakpoints Line Number State is Lost

[interpegasus]

• VSCode Version:Version 1.31.0 (1.31.0)
• OS Version: 10.14.2 (18C54)

Steps to Reproduce:

1. Create a Node.js project
2. Create some breakpoints.
3. Launch the Visual Studio Code built-in debugger

Result
Some breakpoints are erased, and some others change line number.
Usually one breakpoint is automatically added in the first lines of the file.
Breakpoints have to be recreated.

Expected behavior
The app should remember the line numbers, and status of each break point.

Does this issue occur when all extensions are disabled?
Yes

VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* code --disable-extensions

Can your project be shared? If not can you set "trace": true in your launch config, try this again, then upload the log from the path it writes to the debug console?

I have created a sample project without sensitive data. For debugging the breakpoint issue on Visual Studio. Thank you! :

I can't run this, it looks like it's expecting a mongo server or something, how can I run it without that?

/Users/roblou/Documents/BreakPointDebug/node_modules/mongo-express/node_modules/mongodb/lib/server.js:265
        process.nextTick(function() { throw err; })
                                      ^

Good morning,

The project has been updated and the dependency has been removed. https://github.com/interpegasus/BreakPointDebug

The issue can be tested by adding breakpoints inapp.js. After starting/restarting the debugger, the breakpoints are rearranged .

Please let me know in case you have any other questions. Thank you!

[roblourens]

Thanks. You just have to add two lines to your launch config:

"disableOptimisticBPs": true for this issue: facebook/create-react-app#6044 because app.js is the name of the script in the runtime and also the sourcemapped source name.

And "smartStep": false for this issue: #68127
