Changes
In #720, we added the
headersfield on instances ofAuth0Error, with the intent to actually expose theRetry-Afterheaders included in backchannel responses (when theslow_downerror case is hit). This error case is actually producing an HTTP 429 status code, which leads to instantiating aRateLimitErrorinstead of anAuth0Error(the former was not adjusted to exposeheadersin the previous PR).In this PR, I am adding the
headersfield toRateLimitErroras well as setting this field when raising this exception.References
