I'm on Solr 8.3.1 running in non-solrcloud mode.
When I tried to reload an existing core from Admin UI's "Core Admin" by clicking
Reload, after modifying the core's conf/managed-schema, no error was reported.
But the newly added field type is not shown in the core's Analyzer section.
I selected Logging from the side bar, I saw errors like this for every core, not
just the core I tried to reload.

I could not find any mention of custom.vm in any files under any core's conf
directory.
I restarted Solr, the core was loaded without an error and I can see the newly
added filed type.
What could be the cause of these errors that only happens with the Reload
button?
