I can't really test this right now, but looks like it should fix that issue.
BUT, if it doesn't, the code below should do the job for sure.

for commit in commit_data["data"]["repository"]["ref"]["target"]["history"]["nodes"]:
    try:
        if commit and commit["committedDate"]:
            date = search(r"\d+-\d+-\d+", commit["committedDate"]).group()
            curr_year = datetime.fromisoformat(date).year
            quarter = (datetime.fromisoformat(date).month - 1) // 3 + 1

            if repo_details["name"] not in date_data:
                date_data[repo_details["name"]] = dict()
            if branch["name"] not in date_data[repo_details["name"]]:
                date_data[repo_details["name"]][branch["name"]] = dict()
            date_data[repo_details["name"]][branch["name"]][commit["oid"]] = commit["committedDate"]

            if repo_details["primaryLanguage"] is not None:
                if curr_year not in yearly_data:
                    yearly_data[curr_year] = dict()
                if quarter not in yearly_data[curr_year]:
                    yearly_data[curr_year][quarter] = dict()
                if repo_details["primaryLanguage"]["name"] not in yearly_data[curr_year][quarter]:
                    yearly_data[curr_year][quarter][repo_details["primaryLanguage"]["name"]] = {"add": 0, "del": 0}
                yearly_data[curr_year][quarter][repo_details["primaryLanguage"]["name"]]["add"] += commit["additions"]
                yearly_data[curr_year][quarter][repo_details["primaryLanguage"]["name"]]["del"] += commit["deletions"]
    
    except Exception as error:
        DBM.p(f"A exception ocurred while getting the commit history! {str(error)}")
        continue

Thank you @AyushAgnihotri2025!

Merging when?

[thenithinbalaji]

Can you merge it asap?

[pseusys]

I personally can't merge the PR until the CI workflow runs successfully and I also can't launch the workflow. I think, it should be triggered on push. @AyushAgnihotri2025, @willnaoosmith, could you please make sure the workflow runs successfully and, if not, investigate logs and fix errors?

P.S. also, if it's not a big deal, I would prefer if commit is not None: syntax as it is more explicit and clear.

@pseusys it finally did run correctly again!
@AyushAgnihotri2025 Thanks for the help!
