"Session has not been set" error on drush cron

Seeing this error recently for Drupal 10 branch when running
drush sapi-i
for search_api_solr

Is this solvable?

How do you know this is a simple_sitemap issue? Can you provide the full stack trace?

No--I don't have a stack trace, but because the site is in prod, I don't have a good way of debugging it that deeply. I'll check out our other sites and let you know if I see anything that points to Simple XML sitemap...

Same issue, freshly upgraded to D10, indexing the site via UI. Looks like while the batch was running cron also started running, then these messages started appearing.

Type: simple_sitemap
User: Anonymous
Severity: Error
Message: Symfony\Component\HttpFoundation\Exception\SessionNotFoundException: Session has not been set. in Symfony\Component\HttpFoundation\Request->getSession() (line 727 of /code/vendor/symfony/http-foundation/Request.php).

I am also seeing similar errors with Type: search_api.

Maybe it's related to 🐛 Check for session before calling Request::getSession() Fixed ?

I am increasing the priority to Major because it seems that an existing site map is deleted as part of the cron job, but then its unable to regenerate, leaving the site with 404 errors when there is an attempt to retrieve the sitemap.

I am not setting to critical, because the sitemap can be regenerated from the UI (drush fails, even though it reports completed). However, this is not a great solution.

This is still a support request and not a bug report, so changing back the priority. I have the module running on several servers and I'm not encountering this (anecdotal evidence, I know)

This sounds like an exception I used to get when having a space character before the opening php tag, but I might be misremembering.

In any case, I need a full stack trace to debug this. @greatmatter Maybe you're able to clone the environment and reproduce the issue along with a trace?

I just wanted to follow up and report my findings. For me, and likely others, this is due to a change in Symfony\Component\HttpFoundation\Request, which, in current versions of Symfony ,throws the exception if the session can not be found when calling ->getSession(). I found an instance in one of my custom modules, and changed the code to first check ->hasSession() before calling ->getSession(), and the errors go away immediately. Likely the custom code was invoked during cron and drush operations, and causing the exception. I grepped this module for '->getSession()' and I could only find it in the tests, so simple_sitemap is definitely not the culprit.

@scottsawyer - Thank you--this did the trick--found a custom module doing just that. I owe you a beer...

Setting to fixed, since it's a solved support request.
