Failure when logging in / out from Keycloak using FB provider

Hi, we use Keycloak 10.0.2. When I login / logout multiple times using sometimes Keycloak account and sometimes using Facebook provider, sooner or later i get error in Keycloak:

2020-06-09 09:31:25,285 ERROR [org.keycloak.headers.DefaultSecurityHeadersProvider] (default task-14) MediaType not set on path /auth/realms/vi/protocol/openid-connect/auth, with response status 307

which causes 500 exception. Did anybody experience something similar? Can anybody help me and tell how to fix it? Exception stacktrace below:

Maybe this is because of the new “KEYCLOAK-13128 Security Headers SPI and response filter”.
Maybe see https://github.com/keycloak/keycloak/pull/7079 and https://issues.redhat.com/browse/KEYCLOAK-14132 sadly this was rejected :frowning:

Thanks for pointing that out. Maybe now, with my issue, your pull request will be approved. Is there any way I could override this default filter and add 307 to allowed statuses?
