Question: Could not load source 'Fastfile': not found, while debugging a Fastlane lane from VSCODE

[lechuckcaptain]

Your environment

• ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [arm64-darwin23]
• rdbg -v: rdbg 1.9.1

Describe the bug
I'm not an expert here (so I'm probably missing something) but I was recently trying to debug a custom Fastlane lane with rdbg using vscode with the following terminal command:

rdbg --open=vscode -c -- bundle exec fastlane custom_lane

But it seems that the editor cannot load the source file: the Fastfile (see attached screenshot). I would guess that some context information are not correctly passed to the editor (am I missing some parameters?).

If I debug from the terminal, using the following command:

rdbg -c -- bundle exec fastlane custom_lane

Everything seems to work correctly (see attached screenshot).

I prepared an example repo to easily reproduce the issue.

Thanks in advance for your support, and sorry if it's a stupid question 😅

To Reproduce

• Checkout the example repo
• Install the required gems with bundle install
• Debug from terminal with: rdbg -c -- bundle exec fastlane custom_lane
• Debug from vscode with: rdbg --open=vscode -c -- bundle exec fastlane custom_lane

Expected behavior
I would expect to debug the custom_lane similarly from both terminal and vscode.
