I just remembered the issue and relayed the JIRA ;).
As to why I suspect the Java issue, if this was a core Solr issue I’d expect it
to be a show stopper,
Solr isn’t much good if you can’t create cores. Of course weirder things have
happened. Plus,
the date is fine: "2020-07-27T18:02:42.069Z"
If you have the bandwidth, I’d log all the inputs in
ParseDateFieldUpdateProcessor.validateFormatter,
which looks at a glance to be where the exception is caught. The code looks
like this:
public static void validateFormatter(DateTimeFormatter formatter) {
// check it's valid via round-trip
try {
parseInstant(formatter, formatter.format(Instant.now()), new
ParsePosition(0));
} catch (Exception e) {
throw new SolrException(SolrException.ErrorCode.SERVER_ERROR,
"Bad or unsupported pattern: " + formatter.toFormat().toString(), e);
}
}
I suspect the message is a bit misleading and the formatter in that call is
null or some such. Why I
haven’t a clue.
Best,
Erick
