Conf.Language(112)

Error message

Conf.Language(112)

What it means

RenameTag rejects a new tag label containing marker characters (characters with special meaning in SiYuan's tag/hierarchy syntax, e.g. markers checked by treenode.ContainsMarker). The localized message Conf.Language(112) is formatted with the offending character so the user knows exactly which character is illegal.

Solutions

1. Remove the reported invalid character from the new tag name and retry
2. Sanitize the label before calling the API: strip marker characters and verify treenode.ContainsMarker returns ""
3. Pre-validate in the UI/dialog before submitting the rename request

Example fix

// before: new label contains a marker character
newLabel := "project/todo"
// after: sanitized label
newLabel := "project-todo"
if c := treenode.ContainsMarker(newLabel); c != "" { /* reject before calling RenameTag */ }

function assertValidTagName(label) {
  // marker characters must be absent before calling RenameTag
  const markers = /[\\/<>"'|?*:#[\]]/; // extend to full marker set used by treenode.ContainsMarker
  const m = label.match(markers);
  if (m) throw new Error(`tag name contains invalid character: ${m[0]}`);
}

try {
  await fetchPost("/api/tag/renameTag", { oldLabel, newLabel });
} catch (e) {
  if (/invalid character/i.test(e.message)) {
    // extract the offending character from the message and re-prompt the user
  }
}

When it happens

Trigger: Calling RenameTag (via renameTag API, tagRename, or a programmatic caller) with newLabel containing any character returned by treenode.ContainsMarker — e.g. characters that would break tag-tree parsing or block content markers.

Common situations: Paste of text containing markup/markdown special characters into the rename dialog; automation building tag names from arbitrary strings without sanitization; including slash/hierarchy separators where not allowed after trimming.

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
