TYPO3 Core

After further investigation, it seems to come from Flux extension.
Actual TER version breaks all Extbase plugin in a page with circular redirection.

When using the latest development version, there's no more exception.

Hi!
I have a similar strange problem. I use felogin with a custom authentification service (external sso). If a user tries to log in this similar exception appears (maybe the first extension in the "order"). With reload the page the user is loggend in without any errors.

If I deactivate the extension that supposedly causes the error (the first in the "order"), then the next one (felogin) has the problem.

If I deactivate the custom auth service in ext_localconf (ExtensionManagementUtility::addService( ... available => false) and the login with locally users works without errors.

Does your custom auth service does use any kind of extbase ? (repository/model) ? If yes, remove it. Won't work. To early for extbase.

Thank you very much, that was helpful:

Indeed I have added static-info-country repro to the auth service because I have to determine between iso2/iso3 country code.

I had already tried to rollback my code but it won´t work neither - maybe due a cache issue.

Now I have removed all code of dependency incjection and deleted var/cache manually and after that it works again!

V12 comes with core integrated countries. If I remember right, Georg Ringe has a backport of that to v11
as extension. So instead of using static_info_table/extbase you may require that extension and do your check with that ?

Thank you again Stefan, very nice!

In our case, the issue was solved (or worked around) by deleting circular sys_redirects.
