I’m stuck on Stage **File completion** #zv2.

I’ve tried disabling this stage and trying another stage and there I see error that I expect like `job not found` or something relevant. But shell not found, I don’t know, that feels like something that’s not happening because of something I am doing (or maybe it is). Can you please help me?

I made sure that I haven’t changed the `your_program.sh`file or other sh files in the code as well.

Here are my logs:

Hey @vivekjoshi556, I’ve pushed a fix to your repo. You can run `git pull` to sync the changes.

Let me know if you still run into any issues.

Hi @andy1li,

Thank you very much that fixed it. I understand the solution you pushed, but can you please help me understand why was it failing for me and working for other? Is it something I am doing?

Sure! Previously, we ran your program from the repo root directory, so relative paths worked fine

In the Filename Completion extension though, the tester runs your program from a different working directory, so those relative paths no longer resolve as expected.

We updated the starter code to handle this, but existing repos weren’t automatically updated, so this wasn’t your fault at all.
