Help with restoring a deleted pull request

Hi,

I was working in a pull request and deleted all my local files and local git repository.
When trying to get the code from the PR back, I get an error.

So far, I tried to clone the master repository and, inside the directory, checkout the PR.

git clone https://github.com/nf-core/modules.git
cd modules gh 
pr checkout 982

I also tried cloning my personal fork.

git clone https://github.com/asthara10/modules.git 
cd modules gh 
pr checkout 982

The error I get is:

could not determine base repo: fatal: not a git repository (or any parent up to mount point /var/lib) 
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set). 
/snap/gh/453/usr/bin/git: exit status 128

I would appreciate any help, I am new with git.

Thank you very much,

Júlia.
