[SMW-devel] ERROR_SCHEMA_INVALID_KEY

[BREWER, K. M C. U. S. S. DEL/OL-A <kim...@sp...>]

Hello,
I just implemented an extension onto our mediawiki. I updated a deprecated call to wfMemckey() in an extension I am bringing in to the project. After completing this update the wiki now has the following error in staging:

Semantic MediaWiki<https://www.semantic-mediawiki.org/> was installed and enabled but is missing an appropriate upgrade key<https://www.semantic-mediawiki.org/wiki/Help:Upgrade_key>.

Version
Semantic MediaWiki:
4.0.2 (smw:2020-04-18)
MediaWiki:
1.39.1
Code:
ERROR_SCHEMA_INVALID_KEY<https://www.semantic-mediawiki.org/wiki/Help:Setup_check/ERROR_SCHEMA_INVALID_KEY>


I've looked into this and see it has been an issue for a couple of years and I was wondering if a patch or official fix / guide to fix has been released yet? I have tried a few methods to resolve this error and it's not budging. Thank you for your time.
