Michael is exactly correct and we’re off in the weeds here. You submit
an input string and a grammar to the processor, it reports a parse (or
perhaps more than one parse) or no parses, depending on whether or not
that string forms a sentence in the grammar.

No errors have occurred. No exceptions are going to be raised at the API
level in processors with APIs:

  InvisibleXmlParser parser = InvisibleXml.parserFromFile("dates.ixml");
  InvisibleXmlDocument doc = parser.parse("4 Febuary 2022");
  System.out.printf("%d parses found\n", doc.numberOfParses());

Yes, my command line tool will probably “signal failure”, in the sense
of returning a non-zero exit code, if the number of parses is zero, but
that’s between me and my users and has nothing to do with the
specification or “errors” as Michael described them.

                                        Be seeing you,
                                          norm
