Invalid pack ID: {0}

Error message

Invalid pack ID: {0}

What it means

PackDetailPage parses the pack ID from page parameters; a non-numeric ID throws NotAcceptableException with this message. It validates format only — a valid Long that doesn't correspond to a pack will instead fail later in PackService.load.

Solutions

1. Use the numeric pack ID in the pack detail URL.
2. Obtain the ID from the pack object (pack.getId()) when generating links.
3. Fix truncated or corrupted URL segments.

Example fix

// before
String url = "/~packs/" + packName;
// after
String url = "/~packs/" + pack.getId();

if (!packIdString.matches("\\d+")) throw new IllegalArgumentException("Pack ID must be numeric: " + packIdString);
Long packId = Long.valueOf(packIdString);

Long parsePackId(String s) { try { return Long.valueOf(s); } catch (NumberFormatException e) { return null; } }

try { pack = packService.load(packId); } catch (NumberFormatException e) { log.error("Malformed pack id"); }

When it happens

Trigger: Visiting a pack detail URL where the ID segment is not a number, e.g. /~packs/xyz; malformed or hand-edited URLs; code interpolating a package name instead of its numeric ID.

Common situations: Copying only part of a pack URL; scripts using a human-readable package name where the numeric pack ID is required; stale link templates after URL scheme changes.
