Every error jsonata2js can throw carries a JSONata-standard .code (see src/errors.js’s ERROR_MESSAGES, vendored verbatim from jsonata’s own error-code catalogue, plus one jsonata2js-specific addition — U1002, below). This table lists every code in that catalogue. Most are actively thrown by jsonata2js’s own runtime/parser/optimizer/translator; a handful are catalogued but never thrown by this implementation (marked “not thrown” below): D1011/D1012 (jsonata-interpreter-specific — jsonata2js’s own timeout/recursion-depth guard uses U1001 for both cases instead, see README.md’s “Known limitations”), S0206 (this parser never reaches an “unknown expression type” state — every token it fails to parse is reported through a more specific S02xx/S0211 code instead), D1013 (the _jsonata_-prefixed reserved-property-name check is not implemented — reference jsonata itself does not raise it for that input either, so this is a dead code in both projects, not a divergence), and D2015 (“maximum sequence length exceeded” — jsonata2js has no sequence-length cap of its own).
