Why unexpected errors not shows the correct line number in console of vscode?

[NormandoHall]

For instance an SyntaxError error, shows the trace but no the correct line number, usually shows the last or nonexistent line number. For example:

SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at parseJSONFromBytes (/opt/minerva/devel/node_modules/undici/lib/fetch/body.js:580:15)
    at successSteps (/opt/minerva/devel/node_modules/undici/lib/fetch/body.js:520:23)
    at specConsumeBody (/opt/minerva/devel/node_modules/undici/lib/fetch/body.js:529:5)
    at Request.json (/opt/minerva/devel/node_modules/undici/lib/fetch/body.js:368:14)
    at PUT (/opt/minerva/devel/src/routes/tgapp/+server.js:71:30) <------------  error happens at line 61, no 71

    at async Module.respond (/opt/minerva/devel/node_modules/@sveltejs/kit/src/runtime/server/respond.js:279:20)

This happens on every error
