The path sanitation introduced in axios/axios#6810 to solve GHSA-jr5f-v2jv-69x6 likely breaks per route server overrides (ref; https://openapi-code-generator.nahkies.co.nz/guides/concepts/servers-object-handling).
Consider how to solve this without creating a similar vulnerability here.
I believe this can be worked around in the meantime by passing {allowAbsoluteUrls: true} in the axios config parameter / escape-hatch (if you are sure that this won't create a SSRF issue).
