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.
