TypeError: fsStat.Settings is not a constructor

opensearch-dashboards 2.15.0 (upgraded from 2.7.0) on Ubuntu 20.04

Startup fails with the message: TypeError: fsStat.Settings is not a constructor
Then, the plugins and service does a clean shutdown. All the plugins are upgraded to 2.15.0 also.

I’ve tried using a very basic config.yml to eliminate any specific setting in there as the cause, it seems to fail the same way regardless of what’s in the config.

I figured this out. My playbook just unpacked the tar into the existing install path at /usr/share/opensearch-dashboards, which ended up containing files from two versions mashed together. Moving that whole directory and unpacking from the tar into a clean path resolved the issue.
mv /usr/share/opensearch-dashboards /tmp
