We periodically get this error when trying to open a PR

Unable to retrieve default branch: 403: rate limit exceeded
{'message': "API rate limit exceeded for 104.45.204.50. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)", 'documentation_url': 'https://docs.github.com/rest/overview/resources-in-the-rest-api#rate-limiting'}

We're using version 1.0.19 and I don't see any updates that could relate to this in the codebase
