Interpreting Visual Studio Code extension host exceptions in compressed java script

Question

I'm writing a Visual Studio Code extension and ran into problems interpreting exception stacktraces. These are raised from compressed java script code within VSCode and although I do have access to the source code repository in principle, I cannot find the matching typescript line to analyse what is happening. Example:

[2022-02-01 07:53:28.112] [renderer5] [error] Cannot read property 'length' of undefined: TypeError: Cannot read property 'length' of undefined
    at c:\prj\VSCode-1.61.2\data\extensions\ms-python.python-2021.12.1559732655\out\client\extension.js:67:257359
    at p (c:\prj\VSCode-1.61.2\data\extensions\ms-python.python-2021.12.1559732655\out\client\extension.js:67:262355)
    at U.provideCompletionItems (c:\gom\VSCode-1.61.2\resources\app\out\vs\workbench\services\extensions\node\extensionHostProcess.js:94:180703)

So I probably set up some object in a wrong way and the 'length' property is missing. But I have no chance finding the line of code which tries to access it to get a hint which object.

Is there a way to find the matching uncompressed typescript line with the information in that stacktrace ?
