Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] CAUTION: This message originated externally, please use caution when clicking on links or opening attachments! Hi We are testing kolla-ansible 2025.2 and we have found a possible bug in skyline. When using OIDC and trying to log in we get an error that looks like this: { "detail": [ { "type": "string_pattern_mismatch", "loc": [ "header", "X-Openstack-Request-Id" ], "msg": "String should match pattern '^req-\\w{8}(-\\w{4}){3}-\\w{12}'", "input": "", "ctx": { "pattern": "^req-\\w{8}(-\\w{4}){3}-\\w{12}" } } ] } Any help or guidance is appreciated :) -- ---- Taavi Ansper taavi.ansper@cyber.ee
