Key <code>Mentors</code> is missing

Notes:

should we filter out the errors messages for nawiki on Growth Team logstash dashboards?
the current error rate is relatively low, but it's still noticeable. Previously, high error rates raised some alarms - T384775: nawiki down: Error: Typed property GrowthExperiments\Mentorship\Provider\CommunityStructuredMentorProvider::$statusFormatter must not be accessed before initialization.

The same error for pihwiki (also a locked wiki as nawiki) - https://logstash.wikimedia.org/goto/4cff4f51c06f8309dcda602f4ffcd32c

Last occurrence was on 8th April on pihwiki https://logstash.wikimedia.org/app/dashboards#/view/AWl4jlZ78aQffZ3Ho7BV?_g=h@a8ee961&_a=h@11d8633

On nawiki there has been no occurrence in the past 1 month: https://logstash.wikimedia.org/app/dashboards#/view/AWl4jlZ78aQffZ3Ho7BV?_g=h@37b5e18&_a=h@762bf7c

Do we still want to continue tracking this or do we mark it as resolved?

The logstash has some peculiar ways to save urls (if a url is just copied). The above link throws

Error: Unable to completely restore the URL, be sure to use the share functionality.

So, it's better to save links via the menu option Share. And I've updated the task description - added a more general link.

The last error for pihwiki will be on Apr 16, 2025 @ 15:57:5 for mwversion:1.44.0-wmf.25 (`https://logstash.wikimedia.org/goto/3a3627b49cfcd1150712416e3a7c469c)

The last error for nawiki is on Apr 16, 2025 @ 15:55:00.106 for mwversion:1.44.0-wmf.25 (https://logstash.wikimedia.org/goto/8bb90e2e268edb677379bfb837b79ee0)

The errors for nawiki and pihwiki are, basically, logstash noise. Both wikis are in the locked state. The motivation for filing this tasks was twoflod

the initial number of errors was high enough to alarm Release engineers
it'd be good (if possible) to generally solve the problem with not having such errors from wikis that are in a locked state

However, the most recent count - 24 hits in 24 hours (https://logstash.wikimedia.org/goto/cdfb7de00545d5cb8433e625dc6e8388). We may adjust logstash filters to ignore such errors.
