Inconsistent contributions count between requests

[pjmartorell]

Describe the bug
I have a Github Action workflow that fetches the SVG stats from https://streak-stats.demolab.com/?user=pjmartorell&theme=transparent&mode=weekly&hide_current_streak=true&hide_longest_streak=true&border_radius=6&card_width=300
I noticed that the mentioned URL returns different results between exact same calls. See the screenshot below to see the differences.

To Reproduce
Steps to reproduce the behavior:

1. Open the following URL multiple times in the browser: https://streak-stats.demolab.com/?user=pjmartorell&theme=transparent&mode=weekly&hide_current_streak=true&hide_longest_streak=true&border_radius=6&card_width=300
2. Notice that when the result is not a failure, in some cases it returns a very different number of contributions

Expected behavior
The mentioned URL should return always the same result

Screenshots

Desktop (please complete the following information):

• OS: Mac OS Sonoma 14.4.1
• Browser: Chrome, but also fails via cURL
• Version 131.0.6778.109

My hypothesis is that the code calculates the total contributions by fetching data from the GitHub API year by year (since the Github API only allows data retrieval for a maximum period of one year). If some of these intermediate requests fail, the contributions from those years are not included in the total sum.
